5. The data le named robot contains a. time series obtained from an industrial robot. The robot was put through a sequence of maneuvers, and the distance from a desired ending point was recorded in inches. This was repeated 32/1L times to form the time series. (a) Estimate the parameters of an AR(1) model for these data. (b) Estimate the parameters of an ARIMA(0,1,1) model for these data. (c) Compare the results from parts (a) and (b) in terms of AIC
