Abstract

In this paper, we are concerned with truncated distributions that have multiple truncations,  due to being very useful in representing natural phenomena that cannot be studied at all intervals of their growth or development, for example, phenomena that are related to Agriculture, airplanes, health, and the environment.  left truncation is utilized in this study. The statistical characteristics, such as the rth moments, moment generating function, order statistics,  reliability function, hazard rate function, and reversed  Hazard function, have been introduced. triple left truncated exponential distribution has been applied.  Employed the maximum likelihood method to estimate. Also, the performance of triple left truncated exponential distribution was tested by calculating some statistical criteria and testing the goodness of fit for distribution, with comparisons between the distributions and testing them on real data for patients infected with covid-19.
