set_resps: Set responses in an ertmpt_model or a drtmpt_model

Description

Change the responses for a tree and the categories within that tree.

Usage

set_resps(model, tree, categories, values = 0)

Value

A list of the class ertmpt_model or drtmpt_model.

Arguments

model

A list of the class ertmpt_model or drtmpt_model.

tree

Character or numerical value of the tree for which the responses should be changed.

categories

Character or numerical vector identifying category/ies within the specified tree for which the responses should be changed.

values

Numerical vector of length length(categories) providing the responses. Default is 0.
