normal_quadra

Generate Gaussian quadrature points and corresponding normalized weights
based on the standard normal density over a symmetric interval.

Provides functions for computing test reliability and conditional
standard error of measurement (CSEM) based on the methods described in
the Reliability in Educational Measurement chapter of the 5th edition of
"Educational Measurement" by Lee and Harris (2025, ISBN:9780197654965).
