Hi ,
I have a data set and I am trying to get the nonlinear least-squares
estimates of the nonlinear
model parameters .
I have tried nls, gls but seems like i am not able to get it to work. I have
attached the data set.
This is how I am doing. plz lemme knwo how to get it to work
Thanks
mlo.1 <- as.matrix(read.table("sio_co2_mlo_trans.txt",header=T))
y.ppm<-mlo.1[,"mlo"]
t2.yr<-mlo.1[,1] + mlo.1[,2]/13 #decimal fraction
mlo.input<-data.frame(mlo.ppm=mlo.1[,"mlo"],t2.yr=t2.yr)
mod<-nlsModel(y.ppm ~ (C1 + C2 * exp(C3 * t2.yr) + (1 + g * t2.yr) * (a1 *
sin(2*pi*t2.yr) + b1 * cos(2*pi*t2.yr)+ a2 * sin(4*pi*t2.yr) + b2 *
cos(4*pi*t2.yr)
+ a3 *sin(6*pi*t2.yr) + b3 * cos(6*pi*t2.yr) + a4 * sin(8*pi*t2.yr) + b4 *
cos(8*pi*t2.yr))),
data=as.data.frame(mlo.input),start=list(C1=250,C2=20,C3=.05,
g=.04,a1=1,b1=1,a2=1, b2 =1, a3=1, b3=1, a4=1, b4=1))
==============================
using gls ( I dont know how to make the above long equations work in gls.
fm1<-gls(y.ppm ~ t2.yr + sin(2*pi*t2.yr) + cos(2*pi*t2.yr),
data=as.data.frame(mlo.input))

Try this:
pmax(tmax.m[,1], tmax.m[,2], na.rm = TRUE)
