Hello,
In SPSS, a multiple regression can be conducted by inputting the
means, standard deviations, sample size, and correlation matrix
without actually using the raw dataset. Is it possible to do the
same in R?
Thanks in advance for your assistance.
Linda
look at mat.regress in the psych package. It will do some of what
you might want.
That is to say, it will do a multiple regression from the correlation
matrix and give you appropriate tests for the given sample size.
