i am dealing with random number generator and the link below gives information to return random numbers from Normal Distribution but i would like to know how to return random numbers from LogNormal Distribution, Weibull Distribution and Gamma Distribution. Is anyone familiar with this or would be able to give me some advise?

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...

Random question i have a large Excel Workbook (which is protected) and has over five sheets on it - however one sheet has randomly decided not to scroll... yes i know sounds random! If i use the cursor and down arrows the selection just disappears off the screen.
The page will scroll if i filter by one field, but not if i select (All) for all filters.
All other worksheets scroll fine.
Any suggestions?
Thanks in advance.

I'm still new here but after I searched the forum I found great work done
for the needy like me.
So I'm so hopeful
I'm concerned with making a timetable for my school which we used to do it manually
I need a code to distribute each teacher timetable with the following basis:
the number of classes_ the teacher is assinged to work with_multiplied by the number of periods ( which is changeable ).
e.g ; Teacher 1 has 2 classes (1-1 &1-2). Each class should be visited 9 timea a week.
So Teacher 1 should work 18 periods a week
the distribution I need 'd look like the example in Sheet("timetable")
Please don't let me down
any help 'd be greately appreciated

help please
thanks
so I thought I would try again.
Does anyone know of an Excel template--or a small stand-alone
program--that will calculate the interest/principal breakdown when
payments are varied in amount and frequency? Free or low-cost, please.
I need one that will work on my Mac/Office 2004. I will need to print
out periodic reports.
Here is the way the previous poster described it:
"Excel template: Loan Amortization for random/irregular payments,
figures days
between payment dates.
I have a loan with a variable beginning balance and irregular payments
with
annual large payment. (based on collections)
Would like to enter payment and date.
then Excel would figure days since last payment, interest amount,
principal
amount, Ending Principal balance.
And total interest paid, total pricipal paid
If I change the starting principal, excel would recalculate all
entries."
Thanks very much.
Hoping someone can help me quickly as I'm pulling my hair out and have a deadline getting too close.
Been trailing the net and this board but can't work out how to do a simple variance.
How do I work out the difference between two numbers - including negatives.
If the numbers are all positive, it's fine as it's simply a case of A - B = C which is your difference. However, that doesn't work if B is negative.
I need a formula that would give the following:
First Number / Second Number / Difference
1 / 5 / 4
1 / -5 / -6
-1 / 5 / 6
-1 / -5 / -4
-5 / -1 / 4
Hopefully there's a simple function I've been missing.
Thanks in advance, R
i would like to know how to change english numbers to arabic number on excel
, where when i change the language from english to arabic the numbers didnt
changed it still in english
For example my numbers are formatted like this: 1234 and I would like to add zeros to the end so it looks like this: 123400 (no decimal).
I would do it manually but I have a column of over 2000 different numbers.
Thanks for your help, you guys are great!
I need to know the formula (if there is one) for Excel to figure all the possible combinations of a given set of numbers that will add up to a specified sum.
In other words, if I give the following numbers 1, 2, 2, 3, 3, 4, 5, 5, 6, 7, 7 - I want Excel to figure all the possible combinations that will add up to 23, and also SHOW ME those combinations, and not just HOW MANY combinations there are.
i.e. one possible combination is 2, 2, 3, 4, 5, 7
Can this be done? What is the formula? I'm having a hard time figuring it out!!
Desperately,

where each cell/column begins and ends. However there are a few cells where
the break with the next cell does not show the line.
I have highlighed the cell in question, gone to format/cell/borders and
everything looks fine. Black color + format border shows square with all
sides of square showing.
Any thoughts on how to fix these few random cells.
Thanks
I'm a bit of a newbie with Excel, but...
I have several cells with data that contain both letters and numbers (4H, 8V, 4FH, etc.) What I want to do is remove only the text characters from these cells, and add the remaining number values together among a series of cells with this data type.
If your answer involves using a macro or VB, please provide a link on how to use the formula. I've never used a macro or VB.
Thanks.
Here's my question...I have a list of numbers and I want to know how many combinations (and what they are) of adding the numbers will equal an amount.
e.g.
List of Numbers
1
2
3
4
5
6
7
8
9
10
Amount to be reached = 12
These are some of the possible combinations to reach 12 :
2+10
3+9
4+8
5+7
3+4+5
6+3+2+1
Is there a function in Excel that will do this for me? I want to know which numbers (i.e. cells) can be added to reach 12. AND, if possible, colorcode the cells added for each combination.
Good luck and thanks!!
Thanks for any help.

DATA output should be
asd67,h876 --------> 67876
2,3,ujdj5&34 -------> 23534
909k86m34 --------> 9098634
Hope this makes sense?
i have a column of numbers that we extracted from a database as whole numbers. for instance, 30 should be .30 and 100 should be 1.00. when i try to increase or decrease the decimal point it doesn't allow me to convert it to those positions.
would any one have a tip of how i can easily convert this? there are over 2000 entries in my excel spreadsheet so to do it manually would take a lot of time/effort.
thank you!
Im looking for a vlookup formula which will give me the maximum number from a list which contains multiple matches, i.e.
Lookup number 1 from column A, then give me the largest number from column B
example table:
A B
-----
1 5
2 2
1 11
3 2
4 5
the result would be 11
thanks all!

I am working with an Excel spreadsheet and saving it as a .csv file in order to upload to an application that parses out the .csv data as transactions. The system requires .csv files, so this is how I need to save my doc (with this extension). I have been successful at preventing Excel from coverting that long number into scientific format. I have saved as a TXT file, pasted the longer number and it displays correctly. That is all good. But I have to save as a .csv. So if I do that, close the Excel window, and then open again (as the .csv file), the numbers are back to being displayed in scientific format. I have tried creating an Excel doc from scratch and entering text in Text format, to see if this created a cleaner file. But again, the second I save as .csv, close the window and then open that file up again, that dang scientific format is back.
Does anyone have any idea of how to work around this? Once I have successfully gotten the numbers to display as the long-chain number, how can I get them to "stick" so that they don't revert back to scientific format when I reopen the file?
Thanks so much for your help!
