StatTimeSerAnalysis.ARBurgFit Method

#	Name	Description
1	Data	Zero-mean time series. If this is not the case, subtract the mean from data.
2	Phi	Returns estimates for Phi coefficients. AR(p) order is determined by Phi length.
3	Sigma2	Returns Burg estimated variance for AR process.
4	StdErrs	Returns estimated phi coefficients standard errors.

Result: stored in self (calling object)
