In oneinfl: Estimates OIPP and OIZTNB Regression Models

Expected Value for One-Inflated Poisson Distribution

Description

Computes the expected value from a one-inflated Poisson (OIPP) distribution based on the model parameters and covariates.

Usage

E_pois(b, g, X, Z)

Arguments

b	Numeric vector of coefficients for the main Poisson model.
g	Numeric vector of coefficients for the one-inflation process.
X	Matrix of predictors for the main Poisson model, where rows correspond to observations and columns to covariates.
Z	Matrix of predictors for the one-inflation process, structured similarly to X.

Value

A numeric vector of expected values for each observation in the dataset.
