CDF of non-central ${\chi }^2$ distribution revisited. Incomplete hypergeometric type functions approach

Dragana Jankov Maširević, Tibor K. Pogány

The cumulative distribution function of the non-central chi-square distribution ${\chi }_{\nu }^{\prime 2}(\lambda ),\nu \in {\mathbb{R}}^{+}$ possesses an integral representation in terms of a generalized Marcu…
