Zelig (version 3.5.5)

set.start: Set starting values for all parameters

Description

After using parse.par and model.matrix.multiple, use set.start to set starting values for all parameters. By default, starting values are set to 0. If you wish to select alternative starting values for certain parameters, use put.start after set.start.

Usage

set.start(start.val = NULL, terms)

Arguments

start.val

user-specified starting values. If NULL (default), the default starting values for all parameters are set to 0.

terms

the terms output from model.frame.multiple

Value

• A named vector of starting values for all parameters specified in terms, defaulting to 0.

Examples

fml <- parse.formula(formula, model = "bivariate.probit")
D <- model.frame(fml, data = data)
terms <- attr(D, "terms")
start.val <- set.start(start.val = NULL, terms)
