Dear
I had error messages while calculating the covariance matrix in two
occasion. My "x" contains 12 variables:
name ;x=one,d,age,income,age2,income2,excel,vgood,fpoor,male,white,highschl $
While requesting sample covariance with
dstat ;rhs=x ;output=1 $
sample statistics (means, standard deviations, min, max, etc) are
reported, but NOT the covariance matrix. The error message says:
Dialog Error Message:
"Failed to create object,. Make sure the application is entered in
the system registry."
I click "OK" and get another message:
"Out of memory."
Requesting the covariance matrix of OLS estimates encountered the same problem:
regr ;lhs=y ;rhs=x $
matrix ;list ;vb=varb $
This occurred with student computers in which the hard drives are
write-protected. The above worked properly (with no errors) in some
computers, but not with others.
Please help. Thanks.
