Calculating Covariance Matrix From Array In Vba

Right now I have a sports league with 8 teams, I'd like to create a random 7-game schedule where each team plays the other team only once. Essentially this will be a 7-game round robin. However, I'd like to be able to use this for any number of teams and games.

I'd like to do this in Excel, but I can't figure out how to have a randomly generating non-repeating macro with text values in cells.

So right now I have a column of 8 values and need matrix of 7 columns by 8 rows next to it.

I've found this thread that has one for numbers, but I can't figure out how to do it for text values...

Thanks all!

Hello,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:

01/01/2007
02/01/2007
03/01/2007

I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.

Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!

Many thanks,
Caitlin

On my calculator, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get 462,534.50. Which is what I need it to be because I need to calculate the difference of a figure not dividing equally.

On excel, if I divide 462,534.05 by 335 I get 1,380.70. Then if I times 1,380.70 by 335 I get the SAME result of 462,534.05.

I have to account for the difference of not dividing equally so there is some format or accounting function that's preset that I don't want but I have no idea how to fix it or format my excel sheet to calculate as my calculator would.

Please can someone help? Thanks!

I'm trying to come up with a solution to calculate the man hours and days worked over multiple sheets.

I have a file that has 8 sheets. the first seven sheets are the days of the week and the 8th sheet is where I want to calculate the hours.

The days of the week consists of "Name" "Date" Hours"

The 8th sheet consists of "Name", "Days of the week in their own column (7 columns in total)", "Total Hours" and "Total Days Worked"

Now... each day is always a different group and what I'm hoping for is to create a formula that can grab each name with their hours and throw them into the 8th sheet. So when the end of the week is done I have all the Employees weekly hours and days worked all finished.

I hope this makes sense. This file is to track about 100 employees that are on a rotational work schedule.

I have attached a sample file.

Thanks in advance for your help.

I would like the contents of a selected active cell to be displayed in a certain other cell, say R4. When another cell is selected and active, that cell's contents should be displayed.

I have an array of 9 columns and 20 rows with equity symbols and conditionally formatted to show the severity of price movement in either direction.

Instead of typing in the value of whatever cell a trader is looking at I would like for them to just be able to click on the cell and have that symbol copied into R4 so some detailed information can be displayed for them.

Can't find a thing about this on any forum or msdn.

Hope I'm explaining this at least somewhat clearly.

Thanks.

I am trying to work out how to calculate the geometric mean of a series of values, some of which are negative, ie. investment returns over a series of years with some negatives.

The Geomean function doesn't work because it only uses positive numbers.

Any help would be greatly appreciated.

I need a formula to calculate overtime, after a work week of 40 hours.

for example: if an employee works 10 hours a day we would not count towards overtime until the employee completes a 40 hour work week.

Any suggestions would be greatly appreciated!!!!!

Thanks,

I am trying to calculate time based off a non-conventional quarter hour time system

example;
8:00 to 8:07 = 8.0 hrs
8:08 to 8:23 = 8.25 hrs
8:24 to 8:38 = 8.5 hrs
8:39 to 8:53 = 8.75 hrs
8:53 to 8:59 = 9.0 hrs

I am having trouble writing an equation that would sum the clock-in and clock-out times (2 per day) and display the total time in these quarter hours and adding an additional hour if it is >= to *:53. Any help would be great.

I have a spreadsheet with simple (addition/subtraction) formulas. The file is quite large and the formulas are too. All of a sudden, the formulas stopped working except when I double click in the cell containing the actual formula. For example, if I enter "2" in each cell, A2 and B2, cell B3 should reflect "4" because there is a formula in cell B3 which totals cells A2 and B2. Only by double clicking on cell B3 will the program actually calculate. I'm totally perplexed and so is my IT contact. Anyone?

Hi there

I am trying to calculate our On Time Delivery. I want this as a simple percentage of jobs. I have got this running in the following way:

Column M - Estimated Delivery dates
Column N - Actual Delivery dates
Column O - =IF(SUM(M2-N2)>0,1,0)

Then I have calculated On Time Delivery as: =SUM((SUM(O2:O252))/(COUNTA(N2:N252)))

This seems to work fine. My problem is, if we enter a date in Estimated without a corresponding Actual date, the formula for Column O fills out anyway and improves our On Time Delivery Percentage. How can I set this up so that the formula doesn't calculate if there is no data in Column N?

Any help much appreciated

Thanks,

James

I need a formula to calculate Turn Around Time. Find below the sample data and details for your reference.

Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday

If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.

In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

Please let me know if you need any more details

I have a very simple pivot table that I am trying to use as a data source for a VLOOKUP request. Unfortunately, every time I do it I get the result #NA. I have tried recreating the results from the pivot table in the worksheet next to it, and am able to use VLOOKUP on them successfully, but as soon as I point the VLOOKUP array to the pivot table, I get the #NA result

Can VLOOKUP be used on pivot tables? If so, is there any special syntax I need to use?

Thanks

I am trying to calculate the average Talk Time into Minutes and Seconds. Every time I have tried, I get the wrong average.

For example, if I have a total of 53 calls and the total talk time is 4:19:05, what would the average talk per call be? I tried doing everything in seconds (this would give me a total of 15545 seconds) but the total I was getting is 4:89.

What would the formula be to get the correct average time?

Hello,

Please help!!!
We have a client who will pay using the 1/4, 1/2/ and 3/4 of an hour increments as follows:

From the hour mark to 6 minutes = 0 time paid
Over 7 minutes to 15 minutes = 1/4 hour 15
16 minutes to 30 minutes = 1/2 hour 30
30 minutes to 45 minutes = 3/4 hour 45
46 minutes to 60 minutes = one hour.

They work on shifts and the operation is 24 hours. Each gets 30 minutes for breaks which is not paid. Pay is biweekly and overtime is anything over 40 hours. Currently, the template we are using looks like this (sorry, I could not figure out how to paste it so you can see it in Excel layout):
WEEK 1 Sunday Monday Tuesday Wednesday Thursday Friday Saturday
5/16 5/17 5/18 5/19 5/20 5/21 5/22
TIME IN ENTER TIME, INCLUDE AM OR PM
TIME OUT
TIME IN
TIME OUT
TIME IN
TIME OUT
TIME IN Total Hours First Week
TIME OUT
HOURS WORKED-OR- choose one
*HOLIDAY WORKED
PAID HOLIDAY (not worked)
*OTHER PAID HOURS
EXPLANATION OF *HOLIDAY WORKED HRS OR *OTHER

I am very new to Excel and need help creating a formula that will allow us to calculate this timesheet? I am in desperate need for help.

Thanks..
