Details
This function displays trivariate time series plots, i.e. kernel regression
of x_{t-l_1}, x_{t-l_2} against
x_t using functions in the package sm. In particular,
sm.regression is used, with smoothing parameter defaulting
to hnorm(x).
Value
None. Plots are produced on the default graphical device.

sm.regression and, especially,
sm.autoregression in package sm.
