〖〖rx〗(t+12)〗^((k))= α_1 + 〖α_2〗^((k) ) 1(zt≤c^((k) ))+〖β_1〗^((k)) 〖s_t〗^((k))+ 〖β_2〗^((k)) 〖s_t〗^((k)) 1(zt≤c^((k) ))+〖ε(t+12)〗^((k)), That is the regression model
I cant figure out exactly how to input the correct R code for this model using nested minimisation technique

To visualise your 3D data, you can use plot3d and combine it with datetick to format the time axes.

For the auto.arima function in forecast package of R, is there a way to let the function omit a model of arima(0,0,0), as I simply assume there must be some correlation within the dataset.
You could try looking at the help for the function
auto.arima(). Check the arguments start.p, start.q,
d,max.d

I have a vector c("A","B","C",......) and a list list(c("A"),c("B","C"))
I want to get a vector c(1,2,2....)
Is there any function in some basic packages?
we can use merge
merge(stack(setNames(lst, seq_along(lst))), data.frame(values=v1))$ind
