Normal probability plot

Generates a probability plot on Normal scaled probability paper so that the distribution appears linear. Inputs: failures - the array or list of failure times right_censored - the array or list of right censored failure times show_fitted_distribution - True/False. If True, the fitted distribution will be plotted on the probability plot. Defaults to True show_scatter_points - True/False. If True, the plot will include the scatter points from the failure times. Defaults to True. a - the heuristic constant for plotting positions of the form (k-a)/(n+1-2a). Default is a=0.3 which is the median rank method (same as the default in Minitab).

CI - the confidence interval for the bounds. Default is 0.95 for 95% CI. CI_type - time, reliability, None. Default is time. This is the type of CI bounds. i.e. bounds on time or bounds on reliability. Use None to turn off the confidence intervals. kwargs are accepted for the fitted line (eg. linestyle, label, color)

Outputs: The plot is the only output. Use plt.show() to show it.
