This paper proposes a family of distributions Power Series k-Modified from to model sets of count data which have or not any discrepancy in the frequency of observation k in relation to the distribution associated Power Series. Is understood as a modification, inclusion of a parameter in the mass function of probability of the distribution Power Series, making this new family of distributions able to adequately model the data set in cases where there is excess (inflation), poor (deflation) the absence or even when the frequency of the observations k is according to the distribution power series. For this new family of distributions are presented some properties as the distribution functions, Statistics Order among others, besides contextualizes it as mixing model and place it in the context of regression models. The distributions considered for the construction of this new family will be uni-parametric distributions belonging to the Power Series family, whose probability mass function can be written in terms of their average.
