It allows to determine the optimal setof parameters for the program <a href="nstep.html">nstep</a>, whichiterates the local linear model to get a clean trajectory. The givenforecast error is normalized to the variance of the data.<hr><h2 align=center>Usage:</h2><center><font color=Red>onestep [Options]</font><p>Everything not being a valid option will be interpreted as a potential datafile name.
