I want to do regression or missing value imputation by knn. I searched
r-help mailing list. This question was asked in 2005. ksmooth and loess
were recommended. But my case is different. I have many predictors (p>20)
and I really want try knn with a given k. ksmooth and loess use band width to define
neighborhood size. This contrasts to knn's variable band width via fixing
a k. Are there any such functions I can use in R packages?
Your help is highly appreciated.
