Dear all for finding the relation between this variable i use gam ( in base of non-normality)
[1] "temperature" "salinity" "depth" "Clupeidae" model<-gam(Clupeidae~s(temperature)+s(salinity)+s(depth)) the result: Parametric coefficients: Estimate Std. Error t value Pr(>|t|) (Intercept) 0.40156 0.05467 7.345 2.12e-10 *** Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 Approximate significance of smooth terms: Edf Ref.df F p-value s(temperature) 4.321 5.326 1.470 0.207 s(salinity) 2.893 3.569 1.540 0.204 s(depth) 1.000 1.000 0.015 0.903 R-sq.(adj) = 0.1 Deviance explained = 18.9% GCV score = 0.28203 Scale est. = 0.25109 n = 84 this is my question;in base of R-sq. or others parameters,is this model robust ifor analyses? also in others section this parameter is less than0.1 thanks all _______________________________________________ R-sig-ecology mailing list R-sig-ecology@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-ecology
