Extreme values

extval_frechet Calculates the probability (PDF) and cumulative (CDF) distribution functions of the Frechet Type II distribution given the shape, scale and location parameters.
extval_gev Calculates the probability (PDF) and cumulative (CDF) distribution functions of the Generalized Extreme Value (GEV) distribution given the shape, scale and location parameters.
extval_gumbel Calculates the probability (PDF) and cumulative (CDF) distribution functions of the Gumbel (Type I) distribution function given the scale and location parameters.
extval_mlegam Estimates the location, shape, scale and other parameters for the Gamma distribution using maximum-likelihood estimation (MLE).
extval_mlegev Estimates the shape, scale and location parameters for the Generalized Extreme-Value (GEV) distribution using Maximum-Likelihood Estimation (MLE).
extval_pareto Calculates the probability (PDF) and cumulative (CDF) distribution functions of the Pareto distributions (Generalized, Type I, TYpe II) given the shape, scale and location parameters.
extval_recurrence_table Calculates the recurrence interval (return period), cumulative and exceedence probabilities based upon a time series.
extval_return_period Calculates the period of an event (eg, flood, heat wave, drought) occurring given an average event recurrence interval and specified probability level.
extval_return_prob Calculates the probability of an event (eg, flood, heat wave, drought) given an average event interval and a specified exceedance period.
extval_weibull Calculates the probability (PDF) and cumulative (CDF) distribution functions of the Weibull Type III distribution given the shape, scale and location parameters.
