KS test and Spearman correlation: (value, p-value). Estimated parameters of best fit: (parameters, loc, scale). The exponentiated Weibull (exponweibull) distribution shows a probability density function of the form f(x,α,c) = ac[1 − exp(− x^c)]^α−1exp(− x^c)x^c−1 where x > 0,α > 0,c > 0. The lognormal distribution shows a probability density function of the form \(f(x,s) = \frac{1}{{sx\sqrt {2\pi } \exp }}\left( { - \frac{{\log^{2} (x)}}{{2s^{2} }}} \right)\) where x > 0,s > 0
