A scatterplot is an excellent tool for examining the relationship between two quantitative variables. Andrew C. Johnston is a professor of economics at the University of California, Merced. This is confirmed by the PACF plot: Note that the PACF plot has a significant spike only at lag 1, meaning that all the higher-order autocorrelations are effectively explained by the lag-1 autocorrelation. Here we notice that there is a significant spike at a lag of 1 and much lower spikes for the subsequent lags. use http://www.stata-press.com/data/r13/sp500, clear (S&P 500).
