In zhenkewu/slamR: Structured Latent Attribute Models in R

Description

PEM FOR SHRINKAGE - this is to take a candidate latent attribute set

Usage

get_PEM(X, Q, A, lambda, c_ini, g_ini, nu_ini, thres_c, model = "DINA")

Arguments

X	N by J data matrix
Q	J by K structural matrix
A	K-column latent attributes; candidates to be selected!
lambda	negative penalty parameter
c_ini	initial 1-slipping parameters
g_ini	initial guessing parameters
nu_ini	initial potentials
thres_c	threshold for making sure M step does not generate negative probabilities (algorithm 1 of Xu and Gu JMLR 2019)
model	"DINA" (default) or "DINO"

Value

• nu vector of potential ("Delta")

• c 1-slipping parameter

• g guessing parameter
