+% Residuals (or a few other things) from a locfit() fit.
+%
+% Input arguments:
+%   fit - the locfit() fit.
+%   type (optional) type of residuals. Valid types are
+%     'dev'    (deviance, the default)
+%     'd2'     (deviance squared)
+%     'pearson'(Pearson)
+%     'raw'    (observed - fitted)
+%     'ldot'   (derivative of log-likelihood)
+%     'lddot'  (second derivative)
+%     'fit'    (fitted values - no transformation)
+%     'mean'   (fitted values - with back transformation)
