Help me with prediction in linear model
Hi R-community,
I have the code as follows,i Fitted model as follows
lbeer<-log(beer_monthly)
t<-seq(1956,1995.2,length=length(beer_monthly)) #beer_monthly contains 400+
entries
t2=t^2
beer_fit_parabola=lm(lbeer~t+t2)
Below is not working for me.
Please help me in preparing the new data set for the below prediction
predict(beer_fit_parabola,newdata=data.frame(t=seq(1995,1998,length=...

Thanks Murphy and pikal,
I need another help, for fitting first fourier transformation , i used
following thing .Please advise on this
beer_monthl has 400+ records
EXample:
> head(beer_monthly)
beer
1 93.2
2 96.0
3 95.2
4 77.1
5 70.9
6 64.8
time<-seq(1956, 1995.2, length=length(beer_monthly))
sin.t<-sin(2*pi*time)
cos.t<-cos(2*pi*time)
beer_fit_fourier=lm(beer_monthly[, 1]~poly(time, 2)+sin.t+cos.t) #this is
not
wo...
