Optimizer fails, the initial guess will be returned. ‘powell’) and stop once one of the optimizers finds a solution. Try each optimizer in order (‘TNC’, ‘L-BFGS-B’, ‘nelder-mead’, and ‘best’ and the best result will be returned. Will result in that optimizer being used. optimizer ( str, optional) – The optimization algorithm used to find the solution.Regression on X), or ‘RRY’ (Rank regression on Y). Likelihood estimation), ‘LS’ (least squares estimation), ‘RRX’ (Rank method ( str, optional) – The method used to fit the distribution.print_results ( bool, optional) – Prints a dataframe of the point estimate, standard error, Lower CI and.show_probability_plot ( bool, optional) – True or False.
