🚨[WIP]🚨Classes and Algorithms used across Exploratory Diagnostic Modeling Framework

edmcore

The goal of edmcore is to house a set of functions shared by many packages within the exploratory cognitive diagnostic modeling framework.

Installation

You can install the released version of edmcore from CRAN with:

install.packages("edmcore")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("tmsalab/edmcore")

Usage

To use edmcore, load the package using:

library("edmcore")

Overview

The package contains class structure shared between different estimation units.

In particular, we have:

• EDM Classes
  • new_edm_model(), new_edm_summary(), and new_edm_default_property_list().
• Attributes
  • attribute_classes(), attribute_bijection(), attribute_inv_bijection(), attribute_gen_bijection(), and attribute_inv_gen_bijection().
• Q Matrix
  • q_matrix()/as_q_matrix(), read_q_matrix(), is_q_matrix(), is_q_strict(), and is_q_generic().
• Item Matrix
  • item_matrix()/as_item_matrix(), read_item_matrix(), and is_item_matrix().
• Metrics
  • metric_mode(), metric_bias(), metric_frobenius_norm(), metric_element_wise(), and metric_matrix_wise().
• Permutations
• Link Functions
  • link_probit(), link_probit_inv(), link_logit(), link_logit_inv(), theta_to_beta(), theta_probit_to_beta(), and theta_logit_to_beta().
