The\n'Arvind' distribution is a flexible single-parameter continuous\ndistribution on the positive real line characterised by a\npolynomial numerator with Gaussian-type decay. The package\nprovides complete distribution functions (darvind(), parvind(),\nqarvind(), rarvind()), maximum likelihood estimation via\nfit_arvind_mle(), and five model-fitting routines: Random Walk\non Coefficients via fit_rw1(), Time-Varying Coefficient Linear\nModel via fit_tvlm(), Simulation-Extrapolation via fit_simex(),\nMixed-Effects Regression via fit_mixed(), and Regime-Switching\nHidden Markov Model via fit_hmm(). Additionally provides Monte\nCarlo forecasting with prediction intervals via\nforecast_arvind(), comprehensive goodness-of-fit diagnostics\n(21 metrics and 25 plots) via diagnostics_arvind() and\nplot_arvind(), k-fold and rolling-window cross-validation via\ncv_arvind(), and unified model comparison via summary_arvind().\nFor more details see Pandey, Singh, Tyagi, and Tyagi
