AMA: AMA indices

Description

This function calculates the AMA indices: AMAE, AMAV, AMAV and AMAK.

Usage

AMA(data_Bstat, CM, pp_names, steps = 100)

Arguments

data_Bstat

a data frame of dimensions t x 6, here t is the number of temporary steps and each column corresponds to a statistical measure: mean, variance, skewness, kurtosis and excess kurtosis.

CM

A list of arrays, each array corresponds to the conditional moments calculated with the mean, variance, skewness, kurtosis. Each array has dimensions of steps, t, p.

pp_names

vector that contains the names of the parameters (pp)

steps

number of divisions of the parametric range

Value

A list of four matrices, which corresponds to AMAE, AMAV, AMAR and AMAK indices. Each matrix has dimensions of t x pp.
