fit.model: Function to fit the MFDFA result with the extended binomial multifractal model.

Description

function to fit the result of Multifractal detrended fluctuation analysis (MFDFA) with the extended binomial multifractal model. Return the results as a vector which contain the parameters of the model and the goodness of fit

Usage

fit.model(Hq, q)

Value

a vector for fitting parameters."a" and "b" is the coefficients of the extended binomial multifractal model. "Goodness" is the goodness of fit

Arguments

Hq

a nurmeric vector for the generalized Hurst exponent.

q

a vector of integers, q-order of the moment.
