case class AplusBXtoN(input: DifferentiableField, a: Float, b: Float, n: Float) extends DifferentiableField with Product with Serializable

Function that takes an input X and outputs (A + B*X)^N. Cog has two pow() function signatures corresponding to both integer and non-integer powers. The integer case for N is detected here and special-cased (instead of having a separate node for this).

If N is other than a positive integer, be aware that you may need to ensure that the A + B*X term is always positive to avoid NaNs from killing the model state.

a

    Raise a node to a fixed power. Cog has two pow() function signatures corresponding to both integer and non-integer powers. The integer case is detected here and special-cased (instead of having a separate PowN node for this).

    If the power n is anything other than a positive integer, make sure the inputs are always positive or NaNs will result.
