...4 matrix X =289x4 I tried to use the function createX, I know that I have to get design matrix 289x12 (am I right?) but it always says "bad dim" (my code and data in attachment) Where is my fault? Can I use another method in order to create design matrix? Or need it at all here in logmnl (see code in attachment)? Can anyone help me with this issue? Thanks in advance, Tatyana -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
