Cumulative distribution function of the Generalized Logistic probability distribution function, and maximum likelihood fitting function.

pglo(x, para)
parglo.maxlik(x, ini)

`x` |
vector of quantiles for which to evaluate the PDF. |

`para` |
a list of parameters of a generalized Logistic distribution function, as yield by function |

`ini` |
a vector of initial values of the parameters to be fit. |

This functions are used internally by `spei`

and `spi`

and are supposed to never be needed by the regular user. Initial values for maximum likelihood estimation can be provided by `parglo`

.

A vector of cumulative probabilities corresponding to the quantiles in `x`

.
