PCell
class PCell(val parameterName: String, val beta: Double, val targetCategory: Option[Any], val df: Option[Int]) extends PmmlElement
Cell in the ParamMatrix. The optional targetCategory and required parameterName attributes determine the cell's location in the Parameter matrix. The information contained is: beta (actual Parameter value, required), and df (degrees of freedom, optional). For ordinalMultinomial model ParamMatrix specifies different values for the intercept parameter: one for each target category except one. Values for all other parameters are constant across all target variable values. For multinomialLogistic model ParamMatrix specifies parameter estimates for each target category except the reference category.
