the estimates of the parameter (s) are obtained by method of maximum likelihood and the compatibility of PMaD has been discussed using model selection tools such as log-likelihood (-log L), Akaike information criterion (AIC), corrected Akaike information criterion (AICC), Bayesian information criterion (BIC) and Kolmogorov Smirnov (K-S) test. In general, the smaller values of these statistics indicate, the better fit to the data. The point estimates of the parameters and reliability function and hazard function for each data set are reported in Table 6. The interval estimate of the parameter and corresponding asimptotic confidence length are also evaluated and presented in Table 7.

**Data Set-I (Bladder Cancer Data):** This data set represents the remission times (in months) of a 128 bladder cancer patients, and it was initially used by Lee and Wang (2003). The same data set is used to show the superiority of extended maxwell distribution by Sharma et al (2017).\
**Data Set-II : Item Failure Data**\
This dataset is taken from Murthy et al. (2004). It shows 50 items put into use at t = 0 and failure items are recorded in weeks.\
**Data Set-III:** The data set was initially considered by Chhikara and Folks (1977). It represent
