Re: Mean +infinit

[Dr. Oliver Walter]

Good evening,

this problem does not occur if I run a linear regression on my computer. I use pspp 2.0.1 - gb7907d .

There seems to be a problem with some residuals, too. The lowest residual is -8E+307 = -8*10^307 and the highest residual is 1E+308 = 1*10^308. What strange numbers.

Nevertheless, the mean of the residuals of an OLS regression with intercept is always 0. It's an algebraic consequence of the way the regression coefficients are estimated.

The residual standard error (i.e. the standard deviation of the residuals) is given in the regression output.

Kind regards,

Hello,

I have a problem that probably lies in my data and not in pspp. I have calculated a linear regression. It works. Then I want to check the stored residuals. However, no mean value is output, but the frequencies are calculated. The histogram command (via the graphics menu or not) leads to a program crash. Sometimes an error message is displayed, most recently not, stating that there is an error in a file with the end c in a line.

I have looked at everything so often to find the error that I no longer have any idea. I would therefore be grateful for any suggestions.

Thank you.

Greetings

Andreas Hammer
