##### Spark ML -- Survival Regression

Perform survival regression on a Spark DataFrame, using an Accelerated failure time (AFT) model with potentially right-censored data.

##### Usage

`ml_survival_regression(x, response, features, intercept = TRUE, censor = "censor", iter.max = 100L, ml.options = ml_options(), ...)`

##### 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?
- censor
- The name of the vector that provides censoring information. This should be a numeric vector, with 0 marking uncensored data, and 1 marking right-censored data.
- iter.max
- The maximum number of iterations to use.
- ml.options
- Optional arguments, used to affect the model generated. See
`ml_options`

for more details. - ...
- Optional arguments; currently unused.
