Spark ML -- Generalized Linear Regression

Perform generalized linear regression on a Spark DataFrame.

Usage
ml_generalized_linear_regression(x, response, features, intercept = TRUE, family = gaussian(link = "identity"), max.iter = 100L, ...)
Arguments
x
An object coercable to a Spark DataFrame (typically, a tbl_spark).
response
The name of the response vector (as a length-one character vector), or a formula, giving a symbolic description of the model to be fitted. When response is a formula, it is used in preference to other parameters to set the response, features, and intercept parameters (if available). Currently, only simple linear combinations of existing parameters is supposed; e.g. response ~ feature1 + feature2 + .... The intercept term can be omitted by using - 1 in the model fit.
features
The name of features (terms) to use for the model fit.
intercept
Boolean; should the model be fit with an intercept term?
family
The family / link function to use; analogous to those normally passed in to calls to R's own glm.
max.iter
The maximum number of iterations to use.
...
Optional arguments; currently unused.
Details

In contrast to ml_linear_regression() and ml_logistic_regression(), these routines do not allow you to tweak the loss function (e.g. for elastic net regression); however, the model fits returned by this routine are generally richer in regards to information provided for assessing the quality of fit.
