[PersonParameters.jl](https://github.com/juliapsychometrics/PersonParameters.jl) implements estimation of person parameters for Item Response Theory models. Item parameters used in the estimation of person parameters are treated as fixed and known.

It is tightly integrated with [ItemResponseFunctions.jl](https://github.com/juliapsychometrics/ItemResponseFunctions.jl) allowing the estimation for all models defined in the package. Currently these are:

- Models for dichotomous responses

  - 1 Parameter Logistic Model

  - 2 Parameter Logistic Model

  - 3 Parameter Logistic Model

  - 4 Parameter Logistic Model

  - 5 Parameter Logistic Model

- Models for polytomous responses

  - Partial Credit Model

  - Generalized Partial Credit Model

  - Rating Scale Model

  - Generalized Rating Scale Model

Available estimation methods are:

- Maximum Likelihood (MLE)

- Weighted Maximum Likelihood (WLE)

- Maximum A Posteriori (MAP)

- Expected A Posteriori (EAP)
