How to link two rows together? Weights should be tied to returns!!

Hello CB experts! I have a question. It may be simple or it may not; not sure. So, I’m looking for some guidance here. I have historical return on my sheet named ‘Symbols’. In my ‘Returns’ sheet, I have Shares, Return, Volatility, and Weights, along with a Covariance Matrix and a Correlation Matrix on the sheet. I put an Efficient Frontier curve in there and the top performing components of the Dow. I also, have a sheet named ‘Returns-CB’; this is where my CB analysis is. So, from E6:AH6 and E8:AH8, I have defined CB assumptions (they are pretty much all the same). Anyway, my question is this: how do I link the items in row 6 to the items in row 8? If I have 12% return and 30% return for stock AA and stock BA, I should NOT have 0% weight; I want to invest in these stocks. Similarly, if I have a weight of 15% for stock CAT, I should NOT have 0% return. This doesn’t make any sense. Can someone please tell me how to link the returns and weights. It works perfectly fine in the ‘Returns’ sheet; I used MS Solver to get this working. I was trying to do something similar in the ‘Returns-CB’ sheet.
You can download the file from here:

Thanks everyone!!

I know this has something to do with constraints. For instance, Cell C8 must = 100%. Cells E8:AH8 will change, depending on the weights of the stocks (this is contingent on risk; defined assumptions and parameters of the distribution curves). Likewise, Cells E6:AH6 must change, depending on the potential future returns of the stocks (this is also contingent on the risk). It seems like, if I define an assumption, it wipes out any formula that I have in the cell. So, I'm not sure how to 'link' the E6:AH6 range and the E8:AH8 range. Does anyone here have any ideas on this?

How to link two keyevents together ?

I need to detect Shift + 1 and 1 separately, as these two will trigger different tasks. Normal keys like 1,a can be detected in KeyTyped function (KeyEvent.KEY TYPED) and Shift can be detected from keyPressed function (KeyEvent.KEYPRESSED).
But how can I link these two together ?
It is possible that user gives Shift + 1 and then gives 2.
But in my program how can I make out that this Shift is linked to 1 and not to 2 ?

tech_cheetah wrote:
From the APIs I have figured out that I can use this method to check if shift was pressed
public boolean isShiftDown()
The problem with this is that it will still catch sequences such as
[shift down] 2 1 ...
So you wouldn't have the sequence you were looking for, but maybe that's ok?
If you search for my KeyboardCommands class, you'll see there is a way to map arbitrary character sequences (not just shift/control, etc) to an Action. This might be what you're looking for

Linking two computers together

Can I link two macs together so I have access to both but the other computer doesn't have access to mine?

If you own both and have admin accounts on them, yes. On the "other" computer, go to System Preferences, Sharing, and turn on File Sharing.
When the two computers are on the same network, you should see the other computer appear in your sidebar in Finder. Click it, authenticate with your admin details (from the other computer), and you now have access to its files.

Using Sections To Tie Two Rows Together

I use the section capability to join two rows together. I have a button that will duplicate the section. Which on the screen shows perfectly. However, when you save the file, and open it back up it does not maintain those sections. It combines them into one. look at this example:
TABLE 1
ROW 1: element1, element2 -- Row 1&2 are group as a section
ROW 2: element1, element2
User press the add button:
Table 1
ROW 1: element1, element2 -- So when the user press the add button it duplicates the section to add two more rows in order
ROW2: element 1, element2
ROW3: element 1, element2
ROW4: element 1, element2
The user now saves the form and exits...
The user lanuches reader and opens the form. they see the follow result...
ROW1: element1, element2
ROW3: element1, element2
ROW2: element1, element2
ROW4: element1, element2
I need the section to stay together... Any suggestions of what can be done?
Regards

Uncheck the checkbox for the "Repeat Row for each Data Item" in the Bidning tab for Row2 and Row3 inside the Section.
You are actually creating a new instance of the section (which includes Row2 and Row3). So this check box should be checked at the Section levl not at the Row level. You have already checked the Section property so remove from Row 2 and Row3.

How to link two controls?

Hi,
I'm trying to link two controls together, a slider and a numeric, so that if I change the value of one control, the other will also show the new value.
Does anyone knows how to do that? Is that even possible?
Thank you for your help

How to compare two rows in PL/SQL?

Hi All,
How to compare two rows in PL/SQL? Is there any method that I can use instead of comparing them column by column?
Any feedback would be highly appreciated.

If you're talking of rows within a PL/SQL associative array there are techniques as described in the documentation... e.g.

Linking two accounts together

Are you able to link two accounts together. For example, I have had an account for a long time, but now my husband has one as well as my son. My son is currently signed in with my account but I would like to give him his own as well as share what I have with my husband.
Thanks,

Sorry, but it is not possible to merge iTunes Store accounts. You can, however, use content from multiple iTunes Store acounts on any given system or device. You just have to authorize the device to each account. You will have to use the account though which any item was purchased for redownloading, app updates, etc.

How to link two combo boxes? (urgent)

Hello,
I am wondering how to link two combo boxes in Acrobat Pro 9. Basically, I need to link a building with a list of rooms. There are 3 building choices in my first combo box. For the sake of example, Building A, Building B and Building C. When one of the buildings is selected, I want a 2nd combo box to display the rooms that are located in that building. So by selecting building A, you would then be able to choose a room from the list of available rooms in the second drop box. The buildings cannot share a list of rooms because they have the same room numbers. Is anyone able to help?
- Travis

You can also use ajax. When the first combo box element is selected, it will call the ajax function and that ajax function will bring the data from the database and place it in second combo box.

What do you mean with "two rows"? May be two columns??
If the where clause of UPDATE query matches two rows, then it will update two rows. If you want to update two columns, then add column names to your query

It sounds like you should probabally use RMI.That is, remote method invocation...these guys are doing a more complicated version of what you want to do:

How to link two .java files together?

hello everybody,
is it possible to link two or more .java files together? I mean is if I have 3 .java files. (a.java, b.java, c.java) then I have 3 .class files too. How do I use the method in other .java files. For example :
public a extends Applet {
// call b.class
b();
public b extends Applet implements ActionListener {
void title1() {
How to call the b.class? How to call the title1() method?
Is it related to JAR or package??
Thanks for helping me. v(^_^)v

O.K, you do not link ".java" files together.
You compile them into class files and they can create new instances of each other and and access their variables and work together.
I recommend "Sam's Teach Yourself Java in 21 Days".
It will start you out with the basics.

I'm using pages 5.2 and feeling completely stupid by not knowing how to link two text pages together. Can anyone help? please...

Hi there, I'm trying to use pages 5.2 for the first time and I cannot find how to connect two consecutive pages together as I use to do with earlier versions of Pages... Any help?

Word Processing templates have what is called a Document Body.
That is the area defined by the margins and holds a default text area which flows from page to page.
Examples of WP templates are the Letters, Reports, CVs etc.
Layout templates have that switched off and require you to add Textboxes or Shapes into which you can type text. Each page is an individual Section and no text flows from page to page.
Examples of Layout templates are the Brochures, Business Cards, Posters, Newsletters etc
In Pages '09 you can manually link Textboxes to flow in your own set order and across pages. Pages 5 has dropped this along with 100 other features.

How to link two ID account to only one

I have two Apple ID account, and I would like to link them into one account without losing my purchase on both account. How this is possible?

You cannot link two Apple ID's together. You can only log into one and download its purchases, and then log out and into the other account. You should choose one to continue using for the foreseeable future, and hope that someday Apple allows you to link accounts.
