The autocorrelation function correlogram should show spikes close to lags if an arima 2,3 type model generates true data
Added by Whitney C.
Step 1
An ARIMA(2,3) model indicates that the data has an autoregressive component of order 2, a differencing order of 3, and a moving average component of order 0. The differencing order of 3 suggests that the data is differenced three times to achieve stationarity. Show more…

3. An engineer recorded a time series of 100 observations of the quality characteristics of an industrial process. The table below shows the autocorrelation and partial autocorrelation coefficients of the process: k 1 2 3 4 5 6 7 8 9 rk -0.27 -0.29 -0.16 0.28 -0.01 0.25 0.08 0.05 0.02 Ě‘Ď•kk -0.27 0.25 -0.06 0.18 0.14 0.12 -0.12 -0.01 0.02 (a) Identify a plausible ARMA model for the data. (b) Estimate the parameters of the model. (c) After fitting the time series model to the data, the residual autocorrelation coefficients are as follows: k 1 2 3 4 5 6 rk -0.13 0.07 -0.04 0.02 0.08 -0.06 Check the model adequacy by the conventional error band and a goodness-of-fit statistic at the 5% level of significance.

The following two models have been suggested for representing some quarterly data with underlying seasonality. Model 1 Y_t = α Y_{t-4} + e_t Model 2 Y_t = β e_{t-4} + e_t where e_t is a white noise process in each case. (i) Determine the autocorrelation function for each model. [4] The observed quarterly data is used to calculate the sample autocorrelation. (ii) State the features of the sample autocorrelation that would lead you to prefer Model 1. [1] [Total 5]
