conditional density least-squares bandwidth selection
should now work with blocking and generalized and adaptive nearest neighbor bandwidths
however, the convolution kernels still need to be rewritten, as they are mostly incorrect in the cases of generalized and adaptive nearest neighbors
bug fixes for adaptive and generalized nearest neighbors + blocking.
added the correct adaptive second-order Gaussian convolution kernel.
implemented second order adaptive Epanechnikov kernel
tweaked epanechnikov
