FedIRT (version 0.1.0)

fedirt_2PL_data: Federated 2PL model

Description

This function is only used to test the accuracy and processing time of this algorithm. It inputs a list of responding matrices and return the federated 2PL parameters. Note: This function can only calculate one combined dataset. To use federated 2PL in distributed datasets, please use fedirt_2PL().

Usage

fedirt_2PL_data(inputdata)

Value

A list with the estimated global discrimination a, global difficulty b, person's abilities ability, sites' abilities site, and log-likelihood value loglik.

Arguments

inputdata

A List of all responding matrix.

Details

Input is a List of responding matrices from each school, every responding matrix is one site's data.

Examples

inputdata = list(as.matrix(example_data_2PL))
fedresult = fedirt_2PL_data(inputdata)

inputdata = list(as.matrix(example_data_2PL_1), as.matrix(example_data_2PL_2))
fedresult = fedirt_2PL_data(inputdata)
