> GLM predict type should be link or response?
> --------------------------------------------
>
> Key: SPARK-14479

> Project: Spark
> Issue Type: Question
> Components: ML, SparkR
> Reporter: Yanbo Liang
>
> In R glm and glmnet, the default type of predict is "link" which is the
> linear predictor, users can specify "type = response" to output response
> prediction. Currently the ML glm predict will output "response" prediction by
> default, I think it's more reasonable. Should we change the default type of
> ML glm predict output?
> R glm:
> https://stat.ethz.ch/R-manual/R-devel/library/stats/html/predict.glm.html
> R glmnet: http://www.inside-r.org/packages/cran/glmnet/docs/predict.glmnet
> Meanwhile, we should decide the default type of glm predict output in SparkR.
