%description
This function obtains a Random Number Generator (RNG) or collection of
RNGs that replicate the required parameter(s) of a distribution for a time
series of data. Consider the case of reproducing a time series data set of
size 20 that uses an autoregressive (AR) model with phi = 0.8 and standard
deviation equal to 1. When one checks the arima.sin() function's estimated
parameters, it's possible that after a single trial or a few more, one
won't find the precise parameters. This enables one to look for the ideal
RNG setting for a simulation that will accurately duplicate the desired
parameters.
