{title:Residuals vs lagged residuals for time series data}
{p 8 16}{cmd:rvlrplot7} [ {cmd:,} {it:graph_options} ]
{title:Description}
{p}{cmd:rvlrplot7} plots residuals from the last model versus lagged
(i.e. lag 1) residuals. 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}
