Method Detail

censorCol

Param<String> censorCol()

Param for censor column name. The value of this column could be 0 or 1. If the value is 1, it means the event has occurred i.e. uncensored; otherwise censored.

Returns:

(undocumented)

getCensorCol

String getCensorCol()

getQuantileProbabilities

double[] getQuantileProbabilities()

getQuantilesCol

String getQuantilesCol()

hasQuantilesCol

boolean hasQuantilesCol()

Checks whether the input has quantiles column name.

quantileProbabilities

DoubleArrayParam quantileProbabilities()

Param for quantile probabilities array. Values of the quantile probabilities array should be in the range (0, 1) and the array should be non-empty.

Returns:

(undocumented)

quantilesCol

Param<String> quantilesCol()

Param for quantiles column name. This column will output quantiles of corresponding quantileProbabilities if it is set.

Returns:

(undocumented)

validateAndTransformSchema

StructType validateAndTransformSchema(StructType schema,
                                      boolean fitting)

Validates and transforms the input schema with the provided param map.

Parameters:

schema - input schema

fitting - whether this is in fitting or prediction

Returns:

output schema
