El_Badry {popstudy}

El-Badry method

Description

The method corrects the zero parity omission error.

Usage

El_Badry(data, age, CEB, childs, req_ages = NULL)

Arguments

data

data.drame. It contains at least three variables: five-year grouped ages, number of childs and Children Ever Born (CEB).

age

variable name in data of the five-year grouped age.

CEB

variable name in data with number of Children Ever Born .

childs

variable name in data with the number of childs for each five-year grouped age and number of Children Ever Born.

req_ages

optional character string that specifies the five-year grouped age to estimates the intercept.

Value

Moultrie returns a list with two elements: a data.frame with corrected children for each number of Children Ever Born and five-year grouped ages and a data.frame with combinations of five-year grouped age to estimate intercept, slope, and R-squared. By default, the method uses the best value of R-squared to apply the El Badry correction.
