| glm,formula,ANY,DataFrame-method {SparkR} | R Documentation |
Fits a generalized linear model, similarly to R's glm(). Also see the glmnet package.
## S4 method for signature 'formula,ANY,DataFrame'
glm(formula, family = c("gaussian",
"binomial"), data, lambda = 0, alpha = 0)
formula |
A symbolic description of the model to be fitted. Currently only a few formula operators are supported, including '~' and '+'. |
family |
Error distribution. "gaussian" -> linear regression, "binomial" -> logistic reg. |
data |
DataFrame for training |
lambda |
Regularization parameter |
alpha |
Elastic-net mixing parameter (see glmnet's documentation for details) |
