WebMar 31, 2016 · Anyway, I'm pretty sure that you can only use glmnet with S3 classes, so you're going to need to look elsewhere if you want to perform elastic net regression on your data. You could try this package, which does have an elastic.net function. The pdf I linked indicates that the function produces S4 models, so I'd assume that it also takes in S4 data. http://duoduokou.com/python/17559361478079750818.html syria war map news

WebOct 27, 2024 · Pyglmnet is a response to this fragmentation. It runs on Python 3.5+, and here are some of the highlights. Pyglmnet provides a wide range of noise models (and paired canonical link functions): 'gaussian', 'binomial', 'probit' , 'gamma', ‘ poisson ’, and 'softplus'. It supports a wide range of regularizers: ridge, lasso, elastic net, group ...
