...functions or packages for "autoregressive Regressionmodel" with special summaries?. I'm not meaning the function "ar". Example: I have the data working.time <- rnorm(100) # Y vacation <- rnorm(100) #x1 bank.holidays <- rnorm(100) #x2 illnes <- rnorm(100) #x3 education <- rnorm(100) #x3 Now I want to analyse: Y[t] = phi[1]*Y[t-1] + phi[2]*Y[t-1] + ... + phi[p]Y[t-p] + beta1*vacation_t +beta2*bank.holidays + beta3*illnes + beta4*eductation + u_t- Has anyone an idea?
