# Using Bayesian Weighted Method to Estimate the Parameters of Qualitative Regression Depending on Poisson distribution "A comparative Study"

### Abstract

In this paper, we are estimating Weights for parameters models of qualitative regression using Weighted Least Square Method (WLS),which has estimate through inverted variance of the distribution, by two Methods, first one (Classical Method) and the second (Sequential Bayesian Method), when the depended variable is binary variable, and the observations which represented the samples that we take for study distributed non-normality distribution as Poisson distribution, and related to communications have the problem of non-homogeneity variance of random error.

For treatment the problem of heterogeneity of the random error variance we estimate weights used in the way (wls) by two Methods and estimate qualitative regression parameters then comparison between results of Classical Method with Sequential Bayesian Method through some statistic measurements as (MSE, R2, F-test).

Dealt with practical side of the relationship between miscarriages of women as dependent variables and two independent variables, Age of women at marriage and Children ever born ,The data has been taken from Multiple Indicators Cluster (MICS4) survey 2011, the No. of observations was (8024) women where these observations, we noted by using Sequential Bayesian Method we get minimum (MSE) less than the Classical Method in the other side the results of (R-square and F-test) in the Classical Method is better than the Sequential Bayesian Method, We analyzed the data depending on programs written in MATLAB Language and statistics program (SPSS).
