Comparative Study on Logit and Probit Models in the Prediction of Broncho-Pulmonary Dysplasia Status of Infants

Comparative Study on Logit and Probit Models in the Prediction of Broncho-Pulmonary Dysplasia Status of Infants.

ABSTRACT

Broncho Pulmonary Dysplasia (BPD) is a form of chronic lung disease that develops in preterm neonates treated with oxygen and positive-pressure ventilation. The disease affects premature babies and contributes to their morbidity and mortality.

This research seeks to fit and compare the predictive powers of Logistic Regression (Logit) Modeland Probability Regression (Probit) Model in tracking infants’ BPD status using gender and weights at two different time intervals.

The data used for the analysis were samples of 50 infants drawn from an underlying population of children with low birth weight (g) from Ahmadu Bello University Teaching Hospital Zaria.

The children were confined to a neonatal intensive care unit, where they require intubation during the first 12 hours of life, and they survive for at least 28 days and their weights measured four weeks later.

INTRODUCTION

1.1 Background of the Study

The understanding of purpose of statistical science will play important roles to start a research of this kind. Usman (2016), in Bivariate and Multivariate Statistical Analysis, refers Multivariate statistical analysis as multiple advanced techniques for checking relationships among multiple variables at the same time.

Researchers use multivariate techniques in a study that involve more than one response variable (phenomenon of interest) and more than one explanatory variable (also known as a predictor) or both.

The statistical methods comes into play either when we have a medical theory to test or when we have a relationship in mind that has some importance in medical decision or policy analysis in public health.

According to Northway (1967), Broncho-Pulmonary Dysplasia (BPD)is a chronic lung disorder of infants and children and was first described in 1967.

It is more common in infants with low birth weight and those who receive prolonged mechanical ventilation to treat respiratory distress syndrome (RDS).
