The congeneric normal-ogive model is a popular model for
psychometric data (McDonald, R. P. (1997) <doi:10.1007/978-1-4757-2691-6_15>).
This model estimates the model, calculates theoretical and concrete
reliability coefficients, and predicts the latent variable of the model.
This is the companion package to Moss (2020) <doi:10.31234/osf.io/nvg5d>.
