Group by in Jquey in SharePoint designer.

Question

Dear All,
I am trying following jquery for getting all task status of specific user. I want to group by by status and percentage should be calculated as per group by status.
Can anyone please tell me how to group by by Status ?
Expected Result:
Status           Percentage   AssignedTo
In Progress   50%              Harish
Completed    60%              Harish
Unassigned  10%              Harish
Query:
$().SPServices({          
                operation: method,
                async: false,  //if you set this to true, you may get faster performance, but your order may not be accurate.
                listName: list,
                CAMLViewFields: fieldsToRead,
                  CAMLQuery: query,
                      //this basically means "do the following code when the call is complete"
                    completefunc: function (xData, Status) {                 
                        //this code iterates through every row of data returned from the web service call
                        $(xData.responseXML).SPFilterNode("z:row").each(function() {                         
                            //get the title field (Speaker's Name)
                            var Status = ($(this).attr("ows_Status"));
                              //alert(Status);
                            var PercentComplete = ($(this).attr("ows_PercentComplete"));
                            //alert(PercentComplete);                           
                            var AssignedTo=$(this).attr("ows_AssignedTo");
                                 //alert(AssignedTo);                                  
                            arr.push(Status);                           
                            arr1.push(PercentComplete);                  
Thanks,
Harish
