Abstract: In this paper the time that the Internally Displaced Persons (IDPs) took to return from IDPs Camps to their ancestral homes in Northern Uganda was modeled using parametric methods. A retrospective dataset was collected from a cohort of 590 households belonging to seven different villages from Otuke districts that were displaced by Lord Resistance Army (LRA) war and were used in the study for a period of seven years. The raw dataset shows a total of 66 households that have not yet return to their ancestral homes. Stata inbuilt program and Easyfit 5.5 professional software were used to test the distribution (Exponential; Weibull and Log-logistic) fitness for the retrospective IDP dataset. The three distributions fit statistic of Kolmogorov-Smirnov; Chi-Squared and Anderson-Darling were used to test for the distribution fit. The Weibull distribution model was found to have a superior fit for the data than both exponential and log-logistic distribution model since it had a wider acceptance region from the test statistics. The study however recommended the widening of the scope for data collection in future studies for better statistical inference.
