Note that this is not a BIOMOD problem but really a data-algorithm problem. In any case, check the results, they might not be that bad after all. </div><div><br></div><div>Best</div><div>Wilfried</div><div><br></div><div><br></div><div><br></div><div><br></div><div><div>Le 27 oct. 2011 à 21:40, Frederico Mestre a écrit :</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="PT" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: 'Eras Medium ITC', sans-serif; ">Hello:<o:p></o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: 'Eras Medium ITC', sans-serif; "><o:p> </o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US" style="font-family: 'Eras Medium ITC', sans-serif; ">I’m running my models and I keep getting these errors: “fitted probabilities numerically 0 or 1 occurred” and “algorithm did not converge”.<o:p></o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US" style="font-family: 'Eras Medium ITC', sans-serif; "><o:p> </o:p></span></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span lang="EN-US" style="font-family: 'Eras Medium ITC', sans-serif; ">I understand that this means that one of the predictor variables is separating perfectly the values of the dependent variable.
