%description
Implements the Polynomial Maximization Method ('PMM') for parameter
estimation in linear and time series models when error distributions
deviate from normality. The 'PMM2' variant achieves lower variance
parameter estimates compared to ordinary least squares ('OLS') when errors
exhibit significant skewness. Includes methods for linear regression,
'AR'/'MA'/'ARMA'/'ARIMA' models, and bootstrap inference. Methodology
