make_formula: Formula Generator

In bamlss: Bayesian Additive Models for Location, Scale, and Shape (and Beyond)

Formula Generator

Description

Generate a formula for a MVN Cholesky model.

Usage

make_formula(formula, type = "basic")

Arguments

formula	formula.
type	character. Type of Cholesky decomposition.

Details

This is a helper to generate a formula for a bamlss model with k-dimensional multi-variate normal distribution and Cholesky decomposed variance-covariance matrix. It is helpful if one formula should be used for means, another for all diagonal entries of the Cholesky factor, and a third one for all lower triangular entries of the Cholesky factor. The left hand side has k elements separated by |. The right hand side has one to three elements separated by | specifying the formulas used for all means, diagonal entries of the Cholesky factor and lower triangular entries of the Cholesky factor, respectively.
