MCparameter: MC model parameter

In akurz1/tclboot: Conditional Inference in Small Sample Scenarios

MC model parameter

Description

Utilty function to load MC model parameter

Usage

MCparameter(
  N = c(10, 15, 20, 25, 30, 50),
  k = c(6, 8, 10, 12, 14, 16, 18, 20, 25, 30),
  t_inputmat = FALSE
)

Arguments

N	Sample size n of selected case. N = 10, 15, 20, 25, 30, 50
k	Number of items k of selected case. k = 6, 8, 10, 12, 14, 16, 18, 20, 25, 30
t_inputmat	Logical value. If TRUE an initial data sample according to the Rasch model will be generated using function MCsimRasch.

Value

List of MC model parameters and initial data sample..

N	Sample size.
k	Number of items.
splitcr	Split criterion which is a numeric vector x with length equal to number of persons and contains zeros and ones. It indicates group membership for every person.
items	A vector of item parameters of length k. First item set to 0.
filename	Name of MC case. Note: Roman numbers I to VI refer to cases with sample sizes n = 10, 15, 20, 25, 30, 50. Letters A to J refer to cases with number of items k = 6, 8, 10, 12, 14, 16, 18, 20, 25, 30
inputmat	If t_inputmat = TRUE: Initial data sample according to the Rasch model, generated with MCsimRasch.
call	The matched call.
