Islamic inheritance claim processes — Non-normality data traits and best estimator choice

To confront and combat some of the issues in the administration and distribution of Islamic inheritance, Muslims have to look pass constitutional amendments and consider other alternatives as practical solutions to the problem of lengthy and costly claim procedures. Unveiling the uncertainties and confusion undergone by Muslims for so many years has provided the basis for our study to develop the network model and the mathematical model as solution approach to this problem. Careful analysis of variables using normality tests, descriptive statistics, normal and detrended plots as well as box-plots confirms the non-normality of variables, a finding upon which is built the assumption to use median absolute deviation as the best measure of variation to estimate activity durations of the model.
