Hello,
I have not read in much detail this link, but many concepts cited here
belong to what is called 'multivariate linear regression' by the
statistical community.
We already have this procedure in Maxima, you only have to load 'stats'
package.
It is common practice to linerize models with multiple variables by
means of some transformations and variable re-definitions. And then
apply linear regression models.
There is also a function in package 'descriptive', transform_sample,
which might be of some help to transform multivariate data in matrix
format column by column.
For documentation, write
? transform_sample
? linear_regression
