〖〖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

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
