genResponses {conquestr}  R Documentation 
Generates response vectors for n
cases to i
items given
known item parameters, person abilities, and (optionally) other inputs.
genResponses(abilities, itemParams, BMatrix = 1, mcarP = 0, perturbP = NULL)
abilities 
A person by latentdimension matrix of abilities. One column per dimension. 
itemParams 
A list of item params of the structure used in 
BMatrix 
A simplified Bmatrix mapping dimensions (columns) to items (rows). Or the integer "1" if items are dichotomous and ability is unidimensional. 
mcarP 
A double indicating the proportion of missing data under the MCAR assumption. 
perturbP 
A list, where each element of the list contains a data frame referring to an item. Each data frame is either a 1 * 4 data frame describing the general perturbation to apply to the probabilities for that item (currently developed) or a pair of vectors mapping theta to probabilities (not developed). In the first case  the data frame is in this order:

A matrix, n
cases by i
items, of scored item responses.
