Structure Function Analysis in INA: Info & Tutorial

A tutorial on the Structure Function analysis of time series with INA is availbale here: INA_Tutorial7_Structure_Functions_v2.pdf

The structure function (SF) of order q, for the time series is defined as

where τ is the scale and q gives the order of the SF analysis. With INA one can compute the SF for ranges of scales and moment orders q, and also check the monofractal scaling as a linear relationship between the SF slope and the moment order. A screen capture of this functionality is included below together with a tutorial on how to use this INA feature.
