I'm new to JMP scripting and am working on a regression calculation based on an example in the scripting guide.
This script worked for one 64-point X-Y data set, but on a much larger data set, the script is returning "[., .]" for the beta1 variable below ([., .] is being generated by the X`*Y calculation). X and Y are column vectors.
X2 = J(nrow(X),1) || X;
beta1 = Inv(X2`*X2)*X2`*Y;
Can anyone tell me what this output means and/or what may be going on with the script? I have searched this forum and online and have not had success.
