In lgspline: Lagrangian Multiplier Smoothing Splines for Smooth Function Estimation

Cox PH Dispersion Function

Description

Returns 1 unconditionally. Cox PH has no dispersion parameter; this function exists solely for interface compatibility with lgspline's dispersion_function argument.

Usage

cox_dispersion_function(
  mu,
  y,
  order_indices,
  family,
  observation_weights,
  VhalfInv,
  ...
)

Arguments

mu	Predicted values.
y	Observed survival times.
order_indices	Observation indices.
family	Family object.
observation_weights	Observation weights.
VhalfInv	Inverse square root of correlation matrix.
...	Additional arguments (including status).

Value

Scalar 1.
