`data` |
a zoo object with time ordered values of monthly precipitation. |

`scale` |
an integer value representing the time scale at which the SPI will be computed. |

`ini.clim` |
optional, character date of starting point of the reference period used for computing the index (p.e. c("1981-01-01")).Defaults to NULL |

`fin.clim` |
optional, character date of ending point of the reference period used for computing the index (p.e. c("2010-12-01")). Defaults to NULL |

`threshold` |
optional, a negative integer value defining the threashold to use for drought events based on SPI series. Defaults to -1. |

`distr` |
distribution function to standarize data, could be: "gamma","gev" or "genlog". Default "gamma" |

The fitSCI function allow computing the SPI index. Basically, the fitSCI function standardize the precipitation following a Gamma distribution function (i.e., they transform it to a standard Gaussian variate with zero mean and standard deviation of one).
