Caros colegas<br><br>Gerei uma equação da forma = log10(PB)~a+b*log10(PCVZ) o qual relaciona o conteúdo de proteína corporal animal em função de seu peso corporal vazio. Segundo a metodologia que estou seguindo esta equação deve ser derivada para se estimar o conteúdo de PB por Kg de PCVZ. Há uma forma de fazer esta derivada? Alguém poderia me ensinar como fazer?<br>
grato pela atenção.<br><br>modelo5<-lm(log10(PB)~log10(PCVZ),data=PB)<br>summary(modelo5)<br><br><span class="" style="border-collapse:separate;color:rgb(0,0,0);font-family:DotumChe;font-size:13px;font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:15px;text-indent:0px;text-transform:none;white-space:pre-wrap;word-spacing:0px;background-color:rgb(225,226,229)"><pre tabindex="0" class="" style="font-family:DotumChe;font-size:10pt!important;outline-style:none;border-style:none;white-space:pre-wrap!important;margin:0px;line-height:1.2">
