Studies of homozygous PAR2 gene knockout mice have described a mix of phenotypic effects in vitro and in vivo.However, there have been few studies of PAR2 heterozygous (wild-type/knockout; PAR2-HET) mice.The phenotypes of many hemi and heterozygous transgenic mice have been described as intermediates between those of wild-type and knockout animals.

In this paper, a new modification of the Lomax distribution is considered named as Lomax exponential distribution (LE).The proposed distribution is quite flexible in modeling the lifetime data with both decreasing and increasing shapes (non-monotonic).We derive the explicit expressions for the incomplete moments, quantile function, the density ethi
