This function calculates value of the pgf's inverse of the Polya Aeppli distribution.

1 | ```
pgfIpolyaaeppli(s, params)
``` |

`s` |
Value of the parameter of the pgf. It should be from interval [-1,1]. In the opposite pgf diverges. |

`params` |
List of the parameters of the Polya Aeppli distribution, such that params<-c(theta,p), where theta is positive number, and p is probability. |
