Hi

I have a panel workfile (2001 2009 x 3001089 -- 19448830 obs).

When i generate the variable
genr h1=h/h(-1)

i get the error message "Overflow - missing data generated in genr h1=h/h(-1)", the program stops and the variable h1 is generated. (see attached image)

Why does this error message occur? is it because h(-1) does not exist for all observations (if so, shouldnt that just generate nas?).

Is there something wrong with the variable H1 that is generated? (the values looks fine)
Why does the program stop? Can I write a code which forces the program to continue?

What is the minimum value of @abs(h)?

Hi

The minimum value is zero (show @min(@abs(h))). But should not the command genr h1=h/h(-1) just create NAs if h(-1) is zero? If I write show 2/0 i just get a series of NAs.

Try Note that while the error alert shows, x does end up as NA.

Hi

Yes, that is a good thing. But the program stops ...?

Is there a way to write code so that the program will continue even when dividing a series by zero?

Try assigning a higher value to error count:

Hi trubador

thanks. the setmaxerrs worked:

close @all
logmode -error
'seterrcount 1000
setmaxerrs 1000
wfcreate a 2000 2010 300000
genr x=0
genr y=1/x
genr z=2
