Information about the scale parameters of the minimum extreme value distributions such as the Gumbel and theWeibull distributions can help researchers to choose the most suitable value of the location parameter in three-parameter or fourparameter PDFs or CDFs commonly used in forest modelling, such as the Weibull, gamma, Johnson’s SB and beta distributions. This avoids the need to use complicated and laborious algorithms as used for example by Scolforo et al. (2003) and Gorgoso et al. (2012).
