Betreff: st: calculating stdp for interpolation/extrapolation

Hi All,

I would like to calculate 95% CIs for interpolating and extrapolating beyond
a range of estimated values in the data-set. I see from running "predict X,
stdp" that a different stdp is estimated for each value, but I can't figure
out how the stdp is calculated (and thus CI's). 

The following excerpt from the help file does not clarify things for me:
"stdp calculates the standard error of the prediction, which can be thought
of as the standard error of the predicted expected value or mean for the
observation's covariate pattern. The standard error of the prediction is
also referred to as the standard error of the fitted value."

Thanks in advance
