Calculate the maximum score of a set of items

Usage

get_max_possible_total_score(ip, resp = NULL)

Arguments

ip	An Itempool-class object.
resp	(optional) A response vector or a response matrix. The contents are not important. The function only checks whether an element is missing or not. If an element is missing, then that item will not count towards the maximum possible score. If the maximum score of all items are needed, set resp = NULL.

Examples

ip <- generate_ip(n = 10)
get_max_possible_total_score(ip)
# A mixture of dichotomous and polytomous items
ip <- generate_ip(model = c("3PL", "GRM", "3PL", "GRM", "GRM"),
                  n_categories = c(2, 5, 2, 4, 6))
# 1 + 4 + 1 + 3 + 5 = 14
