[R] k-Nearest Neighbour density estimation
Hello!!! I search for a function which does a k-Nearest Neighbour density estimation. I found the package class with the function knn, but this is only an classifier. What i need is: I have a file with one variable which is a score with the range between 0 and 100. The scores occur often, so that we have a histogram. The histogram has gaps, especially at the scores higher than 50. What i like to do is to remap the histogram to fill up the gaps. Than using the knn function: p(s)=(k-1)/N*V(x) to get the density. Example: score: histogram: remaped: 0 2345 2345 1 5678 5678 2 6789 6789 3 0 14 4 0 9999 5 9 6 5 7 9999 ... Thank you for your help and your time.
