Dear list, I have a 4-dimensional array Y of dimension 330 x 67 x 35 x 51. I have a design matrix X of dimension 330 x 4. I want to fit a linear regression of each
lm( Y[, i, j, k] ~ X). for each i, j, k. Can I do it in one shot without a loop? Actually, I am also interested in getting the p-values of some of the coefficients -- lets say the coefficient corresponding to the second column of the design matrix. Can the same be done using array-based operations? I would be happy to clarify if anything is unclear. Many thanks and best wishes, Ranjan ______________________________________________ [email protected] 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.
