Moving Standard Deviation |
Moving Standard Deviation - Excel |
|
So this is what I am trying to do.
I have a list of about 1000 stock price returns in the following format
jan 1 2008 .033
jan 2 2008 .01
jan 3 2008 -.002
jan 4 2008 -.0033
jan 5 2008 .04
What I want to do is calculate in VBA a moving 3 day standard deviation of returns. So I want the first calculation to include jan 1 - jan 3 and place the answer in the cell to the right of jan 3 return. Then move down 1 row and calculate the standard deviation using jan 2 - jan4 and place the answer in the cell to the right of jan 4 return...and so on until the last cell.
Thanks

24 hour format i.e. 15:00. How can I do this?
Is there a way to enter a colon into a standard number to create a value that can be formatted into a 24 hour time value ?
eg a time is listed as 1345 with a general number format, and I want it returned as 13:45 witha custom format of hh:mm.
Other than creating a table and using a vlookup function, I am hoping there is a better way?

Cell B5: start time: 4:15 formatted as 4:15:00 am
Cell B6: finish time: 6:15 formatted as 6:15:00 am
Cell B7: total time: 2:00 formula in cell: =TEXT(B6-B5,"h:mm")
Cell B8: total batches processed: 22 (this is entered manually)
Cell B9: batches per hour: formula in cell: =B8/TEXT(B7,"h")
as long as I have this formula in cell B9 the answer comes out correct which should be 11 per hour.
If the formula in B9 is B8/B7, the answer is 264.0, Is this because of the way excel is reading the total time or the total time is formatted as a time, not an actual number? Is this the correct way to solve the problem?
answer should be 11 per hour.
Are there any ways around this so that it updates upon dragging the formula?
Cells accept hours over 23,
Adding cells in column returns correct total time.
Have not found a way to multiply these cells by a $ hourly rate.
So use HOUR(cell ref) and MINUTE(cell ref) to capture values in referenced
cell - then use these values to calculate total payment for $rate per hour.
However, the HOUR(cell ref) formula returns the hours in excess of 24 when
the cell contains an hour value in excess of 23 (ie 27 hours returns 3).
Could you be so kind as to provide some code that will enable me to display a text box on a userform rounded up to 1 decimal place.
Where am I going wrong....
it calculates the number entered in textbox1 and divides it by a value that changes in cell O26 but the answer is in about 8 or more decimel places.
Only need like 65.3 as an answer not 65.277756942
This is the code ive used.
Private Sub CommandButton1_Click()
TextBox2.Value = Val(TextBox1.Value) / Range("O26").Value
End Sub
A B
312 $1000
54 $1010
35 $1835
32 $1028
53 $1937
=IF(a1=0,"ERROR","")
The trailing "" returns an empty cell. The problem is, it is not TRULY empty. If I fill that formula down, I cannot, for example, jump from one "ERROR" cell to the next by hitting Ctrl arrow-down because it seems to think that these empty cells have contents.
Is there a way to designate, in such a formula as above, to return a TRULY empty cell?
Thanks
date range that was provided, and to return Early, Late or Ok accordingly.
Here is the example.

I'm working with Excel 2003 sp 3 on Windows xp.
I have been banging my head trying to jar loose the formula to calculate man days where 1 equals 8 hours. I have one that was given to me by a coworker:
=INT(Q3/8)+(((Q3/8)-(INT(Q3/8)))*0.8)
That calculates man days from total hours. I need a formula that will total man days and return the man day answer. Example:
weekending 12/25 = 16.2 which is 16 man days and 2 hours
weekending 1/1 = 24.7 which is 24 man days and 7 hours
Total = 41 man days and 1 hour
I have also been asked if there was a way for a number to be entered into a spreadsheet and automatically put in order without a macro or "pushing a button".
Any advice is greatly appreciated!
Happy New Year!

Does anyone know of a way to unhide this macro?
Thanks!
Can somebody help me, i'm new to excel!
Im working with a large data spreadsheet that has Yes and No answers in different columns. There are blanks within the selection too.
I need to calculate only the Yes.
I have tried using the filters in the Pivot Table field list and they are not working.
So now i'm trying to add a COUNTIF formula in the Calculated Fields section.
The formula I'm using is =Countif('Time limit extension'="yes") and i get the answer "too few."
What should I be using in the formula to get the calculated field to work? I have search the whole forum and I haven't found an answer that can help me.
Please HELP!!!
Can you please help me,
A1= time in
B1= time out
C1= time in
D1= time out
I want to calculate the late and under time,
Office start at 9:am w/30 mins Grace period,
The break time is one hour only, please include over breaktime in calculation.
End of office hours 6:00 pm, strickly no over time
Example: I want the answer not-to-exceed $10.00
$6.00 + $3.00 = $9.00
$6.00 + $7.00 = $10.00
I wonder if you could help with this one, I have a list of data like this (no spaces or other characters)
JN551122B
What I need to do is split each of the characters in to its own cell
if JN551122B was in cell A1 I'd want to return:
B2 C2 D2 E2 F2 G2 H2 I2 J2
J N 5 5 1 1 2 2 B
The nearest I have got is the right function, but it brings over the preceeding characters, and I need each character in its own cell. Hopefully I could copy/paste a formula and change the reference for each cell value, i.e. 1 would return J, 2 = N, 3 = 5, 4 = 5 etc.
Thanks for your help!
Many Thanks
