Hello
I'm having trouble figuring out how to use the output of "segmented()"
with a new set of predictor values.
Using the example of the help file:
set.seed(12)
xx<-1:100
zz<-runif(100)
yy<-2+1.5*pmax(xx-35,0)-1.5*pmax(xx-70,0)+15*pmax(zz-.5,0)+rnorm(100,0,2)
dati<-data.frame(x=xx,y=yy,z=zz)
out.lm<-lm(y~x,data=dati)
o<-## S3 method for class 'lm':
segmented(out.lm,seg.Z=~x,psi=list(x=c(30,60)),
control=seg.control(display=FALSE))
Now I would like to create a new set of values between 0 and 100 and
predict the value of the piecewise linear function at those. Would you
please help me figuring out how I would do that?
Thank you so much in advance
claudia
