Github user wangmiao1981 commented on the issue: https://github.com/apache/spark/pull/14818 For example: `LogisticRegression` has `Threshold`, `Thresholds` and `AggregationDepth` etc as parameters. `GeneralizedLinearRegression` doesn't have such parameters. So the interface function(data, formula, family = gaussian, tol = 1e-6, maxIter = 25, weightCol = NULL, regParam = 0.0) should be modified to accept these parameters. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user wangmiao1981 commented on the issue:
https://github.com/apache/spark/pull/14818
@felixcheung If I added it to `spark.glm`, it will break the current
`spark.glm` interface.
`setMethod("spark.glm", signature(data = "SparkDataFrame", formula =
"formula"),
function(data, formula, family = gaussian, tol = 1e-6, maxIter =
25, weightCol = NULL,
regParam = 0.0) `
With this interface, I can't add `LogisticRegressionModel`. I think it is
better to add it to a separate Class, instead of the
`GeneralizedLinearRegressionModel`.

Github user wangmiao1981 commented on the issue: https://github.com/apache/spark/pull/14818 Since `spark.glm` is different from the SparkR `glm` function, adding it to `spark.glm` should be fine.

Github user felixcheung commented on the issue: https://github.com/apache/spark/pull/14818 If we are closely matching the capability of glmnet then we could name it `glmnet` or `spark.glmnet`, if this fits in the existing `spark.glm` implementation (which is different from the SparkR `glm` function) then we should add it there, otherwise our convention would be to add a new function that is named for what it does, such as "spark.multiclassLogisticRegression" From what you have described perhaps it makes sense to add to `spark.glm`? --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.

Github user wangmiao1981 commented on the issue: https://github.com/apache/spark/pull/14818 @felixcheung For Spark, it supports both `binomial` and `multinomial` logistic regression. The link function `logit` under `glm` only supports `binomial`. I found that `glmnet` supports both. There is also a package `mlogit`, https://cran.r-project.org/web/packages/mlogit/vignettes/mlogit.pdf. for `multinomial` only.

Github user wangmiao1981 commented on the issue: https://github.com/apache/spark/pull/14818 @felixcheung https://web.stanford.edu/~hastie/glmnet/glmnet_alpha.html `glmnet` has more functionalities than Logistic Regression (BLOR and MLOR). So `logit` could be a better name. Based on my search R doesn't have `logit`.
