confidence intervals for nls or nls2 model
...el usinf nls function to these data:
> x
[1] 1 0 0 4 3 5 12 10 12 100 100 100
> y
[1] 1.281055090 1.563609934 0.001570796 2.291579783 0.841891853
[6] 6.553951324 14.243274230 14.519899320 15.066473610 21.728809880
[11] 18.553054450 23.722637370
The model fitted is:
modellogis<-nls(y~SSlogis(x,a,b,c))
It runs OK. Then I calculate confidence intervals for the actual data using:
dataci<-predict(as.lm(modellogis), interval = "confidence")
BUt I don?t get smooth curves when plotting it, so I want to get other "confidence
vectors" based on a ne...
