Define a two-stage multistage test

Usage

ty_mst(routing_b, modules, cuts = NULL)

Arguments

routing_b: Rasch difficulties of the routing module, in the order items would be dropped from the end when the module is shortened.
modules: Named list of second-stage modules (difficulty vectors), ordered from easiest to hardest.
cuts: Routing cuts on theta; by default the points where adjacent modules' information functions cross.

Value

A `ty_mst`.

Examples

mst <- ty_mst(routing_b = seq(-1.5, 1.5, length.out = 10),
              modules = list(easy = rnorm(20, -1, 0.5), hard = rnorm(20, 1, 0.5)))
mst$cuts   # where the two modules' information functions cross
