plot(ais.ppr, main="ppr(LBM~ ., nterms=2, max.terms=6)")
## bass: super smoother bass tone control used with automatic span
## selection (see 'supsmu'); the range of values is 0 to 10,
## with larger values resulting in increased smoothing.
plot(update(ais.ppr, bass=5), main = "update(..., bass = 5)")
plot(update(ais.ppr, sm.method="gcv", gcvpen=2),
main = "update(..., sm.method="gcv", gcvpen=2)")
这个画出来的三幅图是什么意思？
