R Documentation

Retention rate of a Q-matrix refinement method

Description

This function computes the proportion of correctly specified q-entries in a provisional Q-matrix that remain correctly specified after a Q-matrix refinement procedure is applied. This function is used only when the true Q-matrix is known.

Usage

retention.rate(ref.Q = ref.Q, mis.Q = mis.Q, true.Q = true.Q)

Arguments

`ref.Q`	the `J \times K` binary Q-matrix obtained from applying a refinement procedure.
`mis.Q`	A `J \times K` binary provisional Q-matrix.
`true.Q`	The `J \times K` binary true Q-matrix.

Value

The function returns a value between 0 and 1 indicating the proportion of correctly specified q-entries in mis.Q that remain correctly specified in ref.Q after a Q-matrix refinement procedure is applied to mis.Q.
