PetscRegressorLinearSetFitIntercept

Set a flag to indicate that the intercept (also known as the “bias” or “offset”) should be calculated; data are assumed to be mean-centered if false.

Synopsis

#include "petscregressor.h" 
PetscErrorCode PetscRegressorLinearSetFitIntercept(PetscRegressor regressor, PetscBool flg)

Logically Collective

Input Parameters

• regressor - the PetscRegressor context

• flg - PETSC_TRUE to calculate the intercept, PETSC_FALSE to assume mean-centered data (default is PETSC_TRUE)

Options Database Key

• regressor_linear_fit_intercept <true,false> - fit the intercept

Note

If the user indicates that the intercept should not be calculated, the intercept will be set to zero.
