Change variable names to be Strings

1

`mixed_models` expects that all variable names (i.e. column indices in the `daru` data frame) are ruby Symbols. However, it would make more sense if the variable names were Strings, because...

It would be great to have a Generalized Linear Mixed Model implementation.

mixed_models currently offers hypotheses tests and confidence intervals for the fixed and random effects of the model with methods #fix_ef_p, #fix_ef_conf_int, #ran_ef_p, and #likelihood_ratio_test. However no significance tests or confidence...

Make LMM#ran_ef_cov and LMM#ran_ef_summary work with interaction effects and categorical effects, [see](https://github.com/agisga/mixed_models/blob/master/lib/mixed_models/LMM.rb#L802).

#symmetric? and #hermitian? for non-dense matrices

4

It is probably not very hard to add Yale and List matrix support to `#symmetric?` and `#hermitian?`. It should go in `nm_symmetric` and `nm_hermitian` in `ruby_nmatrix.c` as far as I...

Support for categorical variables in regression

2

Categorical (as opposed to numeric) variables are ubiquitous in data analysis and linear regression, but they seem not to be supported by `Statsample::Regression`. Here is an example of what I...

`Statsample::GLM.compute` unexpectedly removes the vector, that was used as the response variable, from the input data frame. Here is an example: ``` ruby pry(main)> df.head => # a b c...

The newest version of domainlab cannot be installed with `pip install domainlab` or `pip install domainlab==0.1.9` under Python 3.11 due to the following dependency issue: ``` ERROR: Could not find...
