hi! I hope all of you can help me this question for example GAMs:
ozonea<-gam(newozone~ pressure+maxtemp+s(avetemp,bs="cr")+s(ratio,bs="cr"),family=gaussian (link=log),groupA,methods=REML) formula(ozonea) newozone ~ pressure + maxtemp + s(avetemp, bs = "cr") + s(ratio,bs = "cr") #formula of gams coef(ozonea) # extract the coefficient of GAMs (Intercept) pressure maxtemp s(avetemp).1 s(avetemp).2 s(avetemp).3 s(avetemp).4 s(avetemp).5 s(avetemp).6 s(avetemp).7 s(avetemp).8 s(avetemp).9 s(ratio).1 2.848204561 -0.024662520 -0.095528572 -0.052613005 -0.135309283 0.066243642 0.030937179 0.176267227 0.243405931 0.357027920 0.600628869 0.758581430 0.004653696 s(ratio).2 s(ratio).3 s(ratio).4 s(ratio).5 s(ratio).6 s(ratio).7 s(ratio).8 s(ratio).9 0.156547789 -0.132527837 -0.179947367 -0.208918785 -0.468014803 -0.195498523 -0.813667830 -1.505844690 then, I want to calculate newozone - s(ratio,bs="cr") we define this term (newozone - s(ratio,bs="cr")) is X can i use the coefficient to calculate? -- View this message in context: http://r.789695.n4.nabble.com/Question-about-GAMs-tp3900848p3900848.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
