Hi Andre,
I think you'll have to give some more information about what you want to see on
your plot. The 4 intervals with labels? A bar with an interval maybe? Four bars
with the intervals? Only two showing differences between conf and pred
intervals?
Also you do miss a 1 here I guess:
p_conf1<- predict(ines,interval="confidence",NJ,level=0.99)
p_conf1 #Intervalo de confiança para o estado NJ e para um nivel de 99%
round(p_conf, digits=3)
last line should read p_conf1 here?
Best,
d

Hi Guys,
It's the first time i use R-Help and i hope you can help me.
How can i plot conffidence intervals? with the data bellow:
#Package Austria
library(car)
#head(States)
States1=data.frame(States)
ines=lm(SATM ~ log2(pop) + SATV , data=States1)
summary(ines)
NJ=as.data.frame(States["NJ",c(4,2,3)]) #Identificação do estado NJ
p_conf<- predict(ines,interval="confidence",NJ,level=0.95)
p_conf #Intervalo de confiança para o estado NJ e para um nivel de 95%
round(p_conf, digits=3)
p_conf1<- predict(ines,interval="confidence",NJ,level=0.99)
p_conf1 #Intervalo de confiança para o estado NJ e para um nivel de 99%
round(p_conf, digits=3)
p_pred2<- predict(ines,interval="prediction",NJ,level=0.95)
p_pred2 #Intervalo de perdição para o estado NJ e para um nivel de 95%
round(p_pred2,digits=3)
p_pred3<- predict(ines,interval="prediction",NJ,level=0.99)
p_pred3 #Intervalo de perdição para o estado NJ e para um nivel de 99%
round(p_pred3,digits=3)
Thanks
