Calibrate parameters of multiple log-logist functions using Probability Weighted Moments (PWM) according to Singh (1998) "Entropu-based parameter estimation in Hydrology" (Ch. 18)

Description

Auxiliar function or calculate SPEI and EDDI.

Usage

param_loglogist(var, n_param = 3)

Arguments

var

A matrix or data frame with the variable (hydrologic deficit for SPEI, potential evapotranspitation for EDDI). The data has to be organized with weeks (or desired interval) in rows (e.g. 52 rows) and years in columns.

n_param

Number of parameters of the Log-logist distribution (either 2 or 3).
