Data must have been {cmd:tsset} previously. {p}More precisely, residuals are whatever {cmd:predict, res} produces after a model. The plot is restricted to the estimation sample. {p}{cmd:rvlrplot7} is a renamed clone of {cmd:rvlrplot} 1.0.0 which is for Stata 7. Stata 8 users should use {cmd:rvlrplot} 2.0.0 or later. {title:Remarks} {p}The correlation between residuals and lagged residuals is calculated quietly. This may be retrieved by {cmd:return list} and then (say) used in a second pass giving the correlation on the graph. {title:Options} {p 0 4}{it:graph_options} are options of {cmd:graph, twoway}. {title:Examples} {p 4 8}{inp:. tsset time} {p 4 8}{inp:. regress {it:whatever} time} {p 4 8}{inp:. rvlrplot7} {title:Author} Nicholas J.
