Jurgen may also want to take a look at the -mata- function -runningprod-,
which has a facility to deal with missings:
***********
ssc inst runningprod
clear*
inp byte x
2
3
.
4
2
end
putmata x
mata:y=runningprod(x, 1)
getmata y
l
***********

Hi,
Does any one know how to multiply two or more values located in the same
column but in different rows?
For example, in the first column I have the following information:
Row 1: 2
Row 2: 3
Row 3: 4
Row 4: 2
What I want to do is to calculate:
Row 1 x Row 2 = 6
Previous result x Row 3 = 24
Previous result x Row 4 = 48
Thank you
