fit.model | R Documentation |
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
fit.model(Hq, q)
Hq |
a nurmeric vector for the generalized Hurst exponent. |
q |
a vector of integers, q-order of the moment. |
a vector for fitting parameters."a" and "b" is the coefficients of the extended binomial multifractal model. "Goodness" is the goodness of fit
