options for item parameter estimation

Description

options for item parameter estimation

Usage

estimation_control(
  est = "psychotools",
  resp.cat = NULL,
  use.thurst = TRUE,
  splitseed = NULL
)

Arguments

est	a character value defining the estimation function to use. Possible values: 'psychotools', 'eRm', 'pairwise'.
resp.cat	number of response (answer) categories for all items. If not given, they will be calculated from the data, assuming that every response category is at least once present in the data. Currently only used for pairwise estimations (m parameter in 'pairwise::pair').
use.thurst	a boolean value defining whether thurstonian threshold parameters (TRUE, default) or Rasch-Andrich thresholds (step parameters) will be computed.
splitseed	a numeric value, the seed for random splits in test_waldtest, lest_LR (both only relevant for 'pairwise' or 'psychotools' estimations) and test_mloef (only 'psychotools' estimations)
