Brownian Motion

\description{
The Brown72 data set represents a fractal Brownian motion with
a prescribed Hurst exponent 0f 0.72 .
}
\usage{
data(brown72)
}
\format{
The format is: one column.
}
\details{
``Estimating the Hurst exponent for a data set provides a measure of whether
the data is a pure random walk or has underlying trends. Brownian walks can
be generated from a defined Hurst exponent.''
