Abstract: The convolution ofNadarajah-Haghighi-G family of distributions will result into a more flexible distribution(Nadarajah-Haghighi Gompertz distribution) than each of themindividually in terms of the estimate of the characteristics in thereparameters. The combination was done using Nadarajah-Haghighi (NH) generator. We investigated in the newlydeveloped distribution some basic properties including moment, momentgenerating function, survival rate function, hazard rate function asymptoticbehaviour and estimation of parameters. The proposed model is much moreflexible and has a better representation of data than Gompertz distribution andsome other model considered. A real data set was used to illustrate theapplicability of the new model.
