WebTo visually assess how good the fit is, we'll look at plots of the fitted probability density function (PDF) and cumulative distribution function (CDF). The support of the GEV depends on the parameter values. In this case, the estimate for k is positive, so the fitted distribution has zero probability below a lower bound.
