Table 3 Average difference between maximum likelihood (ML) estimates of \(\alpha\), \(\beta\) and \(\sigma\) and the estimates of these parameters using PRM methods and t test p values for those differences. \(PRM({\overline{D}D}_{\mathrm{g}})\): PRM system of Eqs. (8, 9) applied to the field values of \(\overline{D}\) and \({D}_{\mathrm{g}}\). \(PRM({\widehat{\overline{D}}\widehat{D}}_{\mathrm{g}})\): PRM system of Eqs. (8, 9) applied to values of \(\widehat{\overline{D}}\) and \({\widehat{D}}_{\mathrm{g}}\) obtained from age and site index using the corresponding models. \(PRM({{D}_{\mathrm{o}}D}_{\mathrm{g}})\) and \(PRM({{\widehat{D}}_{\mathrm{o}}\widehat{D}}_{\mathrm{g}})\): PRM system of Eqs. (8, 10) using the field values of \({D}_{\mathrm{o}}\), \({D}_{\mathrm{g}}\) and \(N\) and their predicted values \({\widehat{D}}_{\mathrm{o}},{\widehat{D}}_{\mathrm{g}}\) and \(N\), resp. \(\overline{D}, {D}_{\mathrm{o}}\), \({D}_{\mathrm{g}}\) and \(N\), are the mean diameter, dominant diameter, quadratic mean diameter and stand density. \(\widehat{\overline{D}}\), \({\widehat{D}}_{\mathrm{o}}\) and \({\widehat{D}}_{\mathrm{g}}\) represent predictions of \(\overline{D}, {D}_{\mathrm{o}}\) and \({D}_{\mathrm{g}}\) obtained from the yield table models
