The function lsv is used to estimate the
σ and H parameters of the HKp,
using the LSV (Least Squares based on Variance) method as described in Tyralis
and Koutsoyiannis (2011,Section 2.4).

# Estimate the parameters for the Nile time series.
lsv(data = Nile,k1 = floor(length(Nile)/10),p = 6,q = 50)
