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. The 'PMM3' variant
    (S=3) targets symmetric platykurtic error distributions, reducing variance when
    excess kurtosis is negative. Includes automatic method selection ('pmm_dispatch'),
    linear regression, 'AR'/'MA'/'ARMA'/'ARIMA' models, and bootstrap inference.
