stop.cat: Check if the CAT ended

In simCAT: Implements Computerized Adaptive Testing Simulations

Check if the CAT ended

Description

Check if any stopping rule has been achieved

Usage

stop.cat(
  rule = list(se = NULL, delta.theta = NULL, hypo = NULL, hyper = NULL, info = NULL,
    max.items = NULL, min.items = NULL, fixed = NULL),
  current = list(se = NULL, delta.theta = NULL, info = NULL, applied = NULL, delta.se =
    NULL)
)

Arguments

rule	list with stopping rules se minimum standard error delta.theta minimum absolute difference between current and previous theta hypo minimum standard error reduction hyper minimum standard error reduction after achieving se info maximum information of an available item max.items maximum number of items min.items maximum number of items fixed fixed number of items
current	list with current values se current standard error delta.theta absolute difference between current and previous theta info maximum information of an available item for current theta applied quantitative of applied items delta.se standard error reduction

Value

A list with two elements:

• stop TRUE if any stopping rule has been achieved

• convergence logical. FALSE if the CAT stopped because it achieved the maximum number of items. TRUE for any other case.
