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
