In faffr/calsim: Tools for CAL MST response simulation

Description Usage Arguments Examples

View source: R/rasch_respgen_fun.R

Creates responses based on the Rasch partial credit model.

1	rasch_respgen_fun(pers_ability, item_diff, item_thrsh)

`pers_ability`	is a value equal to the personal ability measure
`item_diff`	is a value equal to the item difficulty.
`item_thrsh`	is a vector of the item thresholds. If dichotomous, item_thrsh will be a single value.

set.seed(1010)
ability = rnorm(1,0,1)  #simulated person ability
difficulty  = rnorm(1,0,1)  #simulated item difficulty

a = rnorm(2, 0, 1)
b = -a
thresholds = c(a, b) #simulated threshold measures
