Generalized Linear Models extension for Statsample
Hi all. Doing `gem install statsample-glm` installs https://github.com/AnkurGel/statsample-glm gem and not this one. Since I'm using bundler I'm going around this using `gem 'statsample-glm, git: 'https://github.com/SciRuby/statsample-glm.git` The same problem happens...
`Statsample::GLM.compute` is failing for certain dataframes. ``` ruby > try = Daru::DataFrame.from_csv 'try.csv' > Statsample::GLM.compute try, 'y', :logistic ExceptionForMatrix::ErrNotRegular: Not Regular Matrix from /home/ubuntu/.rvm/gems/ruby-2.2.3/gems/backports-3.6.8/lib/backports/1.9.2/stdlib/matrix.rb:933:in `block in inverse_from' ``` Get dataframe...
`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...
Statsample-GLM currently takes up a lot of time to fit models. For datasets having 1000 rows it can take hours to fit the model.
I want to talk about two things: **(1)**. `#coefficients(:hash)` return vector names mapping the coefficients but the type of vector names is not preserved. They are all converted to symbols....
Currently most of the testing is happening only for logistic regression. All methods in other forms of regression should also be tested.
