Is there a way to get the following code to include
NA values where the coefficients are NA?
Using a loop, I am running regressions on several
subsets of data1.
reg <- ( lm(lm(data1[,1] ~., data1[,2:l])) )
My regression has 10 independent variables, and I
therefore expect 11 coefficients.
After each regression, I wish to save the coefficients
and standard errors of the coefficients in a table
with 22 columns.
I successfully extract the coefficients using the
I attempt to extract the standard errors using :
For some of my subsets, I am missing data for one or
more of the independent variables. This of course
causes the coefficients and standard erros for this
variable to be NA.
Is there a way to include the NA standard errors, so
that I have the same number of standard erros and
coefficients for each regression, and can then store
the coefficients and standard erros in my table of 22
