`x` |
A dataframe such as generated by getPPP with column names 'data' and 'ppp'. |

`dist` |
A string defining a distribution to be fit. Implemented distributions are "weibull" (default), "lnorm", and "gumbel" (Extreme Value Type 1) |

`npar` |
Number of parameters to evaluate. This really is only looking for potential value of 3 for 3rd parameter optimization. Any other value will resolve the same as default of 2. |

`reg_method` |
A string defining the order of axes presented for regression, whether "XonY" axis(default) or "YonX" axis for alternative study. |

Returns a named vector with parameters of the distribution fit and goodness of fit in terms of R squared.
