lcvplot {locfit} | R Documentation |
The lcvplot
function loops through calls to the lcv
function (and hence to link{locfit}
), using a different
smoothing parameter for each call.
The returned structure contains the likelihood cross validation statistic
for each fit, and can be used to produce an LCV plot.
