create_E_MFI

matrix of the item bank. Rows represent items, and columns
represent parameters. If the model is <code>"GRM"</code>, the first column
represents the <code>alpha</code> parameters and the next columns represent the
<code>beta</code> parameters. If the model is <code>"NRM"</code>, odd columns represent
the <code>alpha</code> parameters and even columns represent <code>beta</code>
parameters

theta_est

vector of number of possible responses for every item

Computes a vector of the Fisher Information of every item allocated to the
specified level node in the CAT decision tree. Every FI is computed using
the estimated ability level in the specified node

Implements the Merged Tree-CAT method (Javier Rodriguez-Cuadrado et al., 2020, <doi:10.1016/j.eswa.2019.113066>) to generate Computerized Adaptive Tests (CATs) based on a decision tree. The tree growth is controlled by merging branches with similar trait distributions and estimations. This package has the necessary tools for creating CATs and estimate the subject's ability level.
