This routine estimate the long-range dependence of a sequence with several methods.

File Information

The most important characteristic of a covariance stationary self-similar stochastic process is that it is long-range dependent. The long-range dependent time series hold significant correlations across arbitrarily large time scales. And the Hurst parameter H measure the degree of long-range dependence and can be estimated by several methods.

Hi chu.

What methods have you used to generate the input sequence?I have used your codes, and in higuchi methode I found hurst parameter greater than 1 and in more methods I found hurst parameter least than 0.5.please tell me why?thanks

hi chu,
I had some H greater than 1 when i run this code. could you tell why? thx

Great peace of code! I was looking long time around to find it.
- Maybe the various methods could briefly be summarized so that terminological variations can be cleared.

Hi Chu,

I would like to estimate the Hurst coefficient so I can determine if my data series is persistent (H>0.5), antipersistent (H<0.5), or neutral (H=0.5). Several of the estimates I get are, for example, H = 1.8, or H=1.6, H=0.9....should I disregard the whole number and concentrate only on the decimals for interpreting persistence?

I have used your RS routine, and in some cases I found hurst parameter greater than 1 (one), is it anything wrong? Thanks.

Good job, usefull package to esitmate Hurst coef, thanks

very good, and contain different methods to estimate hurst parameter

A very good package combining different methods. Recommended for studing purposes and developpment of own algorithms
