Does default sample size affect modeling?

when i tried to apply data contained in a table to a model, I noticed that the data table was sampled and sampled data was applied to model instead of applying all data to a model. THis is decided by Default Sample Size specified in Preferences. I wonder when we build a model, does oracle also sample part of original data and only use sampled data to build the model?
thanks

Hi,
Are you referring to using Data Miner 10.1?
If so, the Preferences, sample setting is used only for statistics gathering.
There are two ways to build or apply a model in Data Miner 10.1.
1. Using build or apply wizard.
2. Using build or apply activity.
The build activity does have a sample step but it is up to you whether to run it or not.
Neither the apply activity or apply wizard perform sampling.
Can you explain what makes you think that the apply process is sampling data?
Thanks, Mark

Default Sample Size in ODM

The default sample size for Summary Statistic (Show Summary Single Record) is 1000 cases. We understand that we can change the default sample size at Tools --> Preferecnes --> Sampling. However, we would like to know what is the limitation on sample size/maximum cases a user can key in?
Hope someone can provide me the answer. Thank you.

I believe that you can enter as many rows as the number of rows in the data. The larger the sample size the more expensive it is to compute the stats as it needs to do more work.

andrew KainIts good to mention the db version that you are referring to. With 10g, the sample size has been automated and oracle picks up the value on the fly by itself. Mention the version please before e comment.

Does the pixel size affect printing in iphoto?

Have trouble printing in iphoto. I can view the photo in iphoto fine. When I print, I am just getting a small corner of the picture. Can the pixel size affect printing?

Set your ruler increments to pixels Preferences>Units & Increments. You can fill the text box with placeholder text Type>Fill with Placeholder text and get a word count from the Info panel with Show Options turned on from the flyout.
From the Transform panel you can set a text box's width and height

Sample size does'not appear in QA02 of created Inspection lot Number.

Hi Experts,
I have created a production order of a material and its Inspection lot is automatically created but the inspection lot created does'not have sample size from the stock as a result I am unable to perform result recording of a inspection lot.
Please correct me if i am wrong.
Thanks
Saurabh

Dear Saurabh Mishra.
Kumar & Barjatya's said is right. and more you can consider for solve this problem as below step;
- You must change the sampling procedure in the inspection plan. After you have reset the sample
in QAC3
    1. First you must change the sampling procedure to fixed sample (assuming you have 100%
        inspection at present) in QDV2 or
        create a new sampling procedure (as Naik remarked) with fixed sample in QDV1
    2. Then assign the changed sampling procedure in the inspection plan through QP02
    3. Then assign a sample quantity in the inspection plan in the same transaction (QP02) for the
        inspection characteristic to be inspected
    4. Save the inspection plan, and run QA02 where you re-assign the updated inspection plan and
       re-do sample calculation.
       For GR based lot i have already stated what has to be done. In case of an inspection lot caused
       due to the GR from a process or purchase order, cancel the GR. The inspection lot is also
       cancelled. Then follow steps 1 to 3. In the 4th step after saving the inspection plan, simply do the
       GR again, It should work out.

How do I change the default paper size in Firefox if Printer Properties does nothing?

I print on different including a receipt printer with roll paper.
I had to reset Firefox yesterday because of a bug, and then changed the Printer Properties to be able to print again in the right format on the receipt paper. But now everything I print from Firefox (even when I change the paper size to Letter on the Printer properties for the regular printer) is in the receipt paper format (long and narrow.) When I do Print Preview, I can see that the paper looks like the roll paper, even if I'm trying to print on letter size.
I tried resetting both printers with about:config, I tried changing in the printer properties for both printers and nothing works.
Is there a way to change the default paper size in Firefox?

Hello,
My understanding is that Firefox uses the global printer settings. I am not familiar with the Windows 8 interface, but can you change the printer settings in its Devices and Printers and see if it changes the default for Firefox as well?

How come inspection points with DESTRUCTIVE MICs don't affect sample size?

Hi guys,
i have a case i tried on IDES and i need an explanation for it if you can.
@ the beginning we have an in-process inspection with inspection points and non-destructive MICs, the interval of 10 mins (of the inspection point) generated 3 inspections, and my sampling procedure led to a sample size of 1 PC, in the inspection lot display the sample size is "1", which is normal and i understand this.
here comes the problem
we will change one of the MICs and make it destructive. Now we have our 3 inspections. The normal logic says that I'm having 3 inspections and there is on of the MICs DESTRUCTIVE, therefore I'm must get 3 samples, one for each inspection, which means that when we check the sample size in the inspection lot we must get a size of 3, but when i tried this i got a size of 1 again....and this is not logical because my sample will be destructed in the first inspection so how can I carry on the remaining 2 inspections ???
so i need to know how come I'm getting a size of 1 and is that right or wrong ???
i hope i made it clear and wish you can help
Regards,
Mahmoud Osama

Hi Amol,
i'm sorry i don't understand what do you mean by operation confirmation quality ???
and about stock posting, i know as you said that it is not possible with in-process inspection, as the lot is not stock relevant, but whether it is stock relevant or not has nothing to do with the sample size calculation, my problem is that the logic says that i must get 3 samples because with each inspection i'll destruct my sample, but SAP calculations give only one sample !!!!
i hope you can help with that, thanks for you concern.

Mahmoud Osama

How do I set default font size?

Some programs (most importantly for me, Thunderbird) use a default font size that is too small for my eye comfort. Some (such as Firefox) allow me to change the font size, but Thunderbird does not (though there is a menu item to change font size, which does not work).
I gather that such programs are using a default system font size. So I would like to change this. Some Help articles suggested that I could do this from the Font Panel, but they give no indication where to find the Font Panel. I cannot find it in System Preferences or via the Spotlight.
I am using OS X 10.4.7
I am computer-literate, but new to the Mac, having had this computer for about a week and a half.
P.S. In Thunderbird -> Preferences -> Fonts there is an option to configure the fonts used by Thunderbird. The settings affect messages, but not the main window with the message list. However, at this point I'd really like to set the system default so all programs that use the system default will be affected.
Thanks.
Daniel

This still does not work.
I tried all of them.
Theme Font & Size Changer
Big Buttons
Default FullZoom Level
NoSquint.
It only works for that page of that web site, as soon as you leave you start all over again.
Can't we just say Firefox messed up and needs to revert to the way it used to work without have to do ANYTHING to adjust any sizing.
This is utterly ridiculous.
It's a web browser for GOD sakes...not the OS. It shouldn't be doing anything but displaying web sites with NO INTERVENTION by the user for each and every page.
Why are programers always looking for ways to take a working product and make it useless???

How do I find, at-a-glance, the sample size used in several music files?

How do I find, at-a-glance, the sample size used in several music files?
Of all the fields available in a FInder Search, "Sample Size" is not available. Finder does offer a "Bits per Sample" field, but it only recognized graphic files and not music files.
Running 10.8.5 on an iMac i5.
I did search through a couple of communities but came up empty.
Thank you,
Craig

C-squared,
There is no View Option to allow display of a column of sample size.
For WAV or Apple Lossless files, it is available on the Summary tab (one song at a time, as you know). For MP3 and AAC it is not available at all.
You can roughly infer it from the files that are larger than expected for their time.
99% of the music we use is at the CD standard of 16-bit, so I can guess that displaying it has never been a priority. However, if you want to make a suggestion to Apple, use this link:

How to change default window size?

I'm using MX 6.0 on Mac... For some reason I can't figure out
how to change the default window size in the work windows. Every
time I open a new file to work on it opens to a smaller size than
the actual page is. When opening pages dozens of times a day, it
gets annoying to have to resize each time. I'm sure it wasn't
always like this, but I can't figure out how to change it so the
default size that it opens to each time is larger.
Thanks for any help,

How to change the default font size in X11?

I was a PC/linux user and have switched to use Mac lately (MBP Snow leopard 10.6.8).
Everything's been running perfectly on Mac so far and I really like it, until I have to run some programs on XQuartz/X11 (XQuart 2.7.0).
The default font size in the Xterm is too small. And I hate it that I have to change it everytime i open a new terminal (via vt fonts menu, ctrl+right-mouse click).
Is there a way to change the default font size "permanently" in XQuartz/X11 ??
This may be a stupid question to ask in the developer forum but i cant really solve it.
There's only config. file ~/.Xdefaults they have mentioned so far on Google but i really cant find it regarding to the directorty.
Thank you very much in advance.

You would be surprised to find out that is not like this, to get your account blocked you really need to do a lot of damage and posts are not removed unless they are illegal, and *always* it needs more than a person to delete something. That's a site managed by the community, not by some people put in place by a company.
It is always acceptable to link to external resources as long these resources do provide additional usefull information. Clearly the thread on that side contained much more information than the one here. I observed people linking from there to this forum, but it's not so common, and that's not due to the policy, just because here is more chat and less usefull information.... you will not see endless threads of replies on with "yes, I have the same problem" there.
Shortly, this is "discussions" and is quite different in approach than the SE model, where everythign is aimed towards getting the be answers UP and removing all the nonsense.
I wish that Apple would invest more in discussion, and going towards making this more practical.

What is the best way to verify default heap size in Java

Hi All,
What is the best way to verify default heap size in Java ? does it vary over JVM to JVM . I was reading this article http://javarevisited.blogspot.sg/2011/05/java-heap-space-memory-size-jvm.html , and it says default size is 128 MB but When I run following code :
public static void main(String args[]) {
int MB = 1024*1024;
System.out.println(Runtime.getRuntime().totalMemory()/MB);
It print "870" i.e. 870 MB.
I am bit confused, what is the best way to verify default heap size in any JVM ?

Hi Kayaman,
Sorry but I don't agree with you on verification part, Why not I can verify it ? to me default means value when I don't specify -Xms and -Xmx and by the way I was testing that program on 32 bit JRE 1.6 on Windows. I am also curious significant difference between 128MB and 870MB I saw, do you see anything obviously wrong ?That spec is outdated. Since Java 6 update 18 (Sun/Oracle implementation) the default maximum heap space is calculated based on total memory availability, but never more than 1GB on 32 bits JVMs / client VMs. On a 64 bits server VM the default can go as high as 32gb.
The best way to verify ANYTHING is to address multiple sources of information and especially those produced by the source, not some page you find on the big bad internet. Even wikipedia is a whole lot better than any random internet site IMO. That's common sense, I can't believe you put much thought into it that you have to ask in a forum.

Can you adjust the Sample Size in LR?

In Photoshop, you can set the size of the eyedropper to sample a single pixel, 3x3 average of 9 pixels, 5x5, 11x11, etc. It can make a big difference when sampling a single pixel as opposed to the average of a larger area.
Can the sample size be set in LightRoom?
If not, what is the sample size in LR when you run your cursor over the image? Does this vary depending on the displayed magnification of the image?
Thanks,
Lou Dina

White Balance and the Color Sampler are not the same unless things have changed. White Balance is always 5x5 image pixels while the Color Sampler is 5x5 screen pixels. Therefore, one can increase the
accuracy of the color sampler by zooming in beyond 1:1. In the case of White Balance, I don’t think that’s true, again, unless that's been recently changed. Yes, kind of confusing. Bottom line though, zoom in to do precise work.

Default paper size in page setup

I have 3 different printers, each with specific paper sizes. My HP C3180 uses letter size only. My HP Officejet pro K850 uses tabloid (ledger) size only. My Toshiba e-studio 20s has a tray for letter and another for tabloid. My problem is that when I set the default paper size in page setup, it changes the paper size for all three printers! How do I set a different default paper size for each individual printer?

Thanks. I'm really disappointed that apple had to dumb-down Leopard. It really makes it difficult to use my macs in the office. I hate to say it, but score one for the PC on this one. I'm really frustrated, and this will definitely affect future purchases (Apple, did you hear that?)
Thank you.
