Application of Wilks’ Lambda and Hotelling’s with MANOVA on Drug Addiction and Drug Abuse Data

Abstract

In this study Wilks’  Lamda and Hotelling’s  were employed as Multivariate Analysis of Variance (MANOVA) technique in determining the significance difference in the causative factor for drug addiction and abuse. The data were primary and were generated by a survey conducted on some patients selected from Neuro-Psychiatric Hospital Enugu-Nigeria.  The patients were divided into two groups - those treated of substance  abuse before and those treated for the first time. 89 patients were selected  and nine factors  for substance abuse were considered. They were rated and scored over ten by the patients. The result showed  a significant difference in the factors specified for drug abuse. .
