LC2LG {GDINA} | R Documentation |
Transformation between latent classes and latent groups
Description
This function gives the equivalent latent classes which have the same category success probabilities for each category or item.
Usage
LC2LG(Q, sequential = FALSE, att.str = NULL)
Arguments
Q |
A required |
sequential |
logical; whether the Q-matrix is a Qc-matrix for sequential models? |
att.str |
attribute structure. See |
Value
An item or category by latent class matrix. In the G-DINA model,
if item j measures attributes,
latent classes can
be combined into
latent groups. This matrix gives
which latent group each of
latent classes belongs to for each item.
