I have installed Hmisc and Design. When I use ols, I get the
following error message:
Error in if (!length(fname) || !any(fname == zname)) { :
missing value where TRUE/FALSE needed
The model that I am running is:
> ecools <- ols(eco$exp ~ eco$age + eco$own + eco$inc + inc2, x=TRUE)
I have tried several other combinations of arguments that take TRUE/
FALSE values, but no luck.
Ultimately, I am trying to calculate robust standard errors.
Any help would be appreciated.
