Is there a way to get the following code to include liens where the coefficients are NA?
((summary(reg))$coefficients) explanation: Using a loop, I am running regressions on several subsets of data1. reg <- ( lm(lm(data1[,1] ~., data1[,2:l])) ) My regression has 10 independent variables, and I therefore expect 11 coefficients. After each regression, I wish to save the coefficients and standard errors of the coefficients in a table with 22 columns. I successfully extract the coefficients using the following code: reg$coefficients I attempt to extract the standard erros using : aperm((summary(reg))$coefficients)[2,] ((summary(reg))$coefficients) My problem: 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 columns? ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
