Hey there, I have the following problem: I need to carry out a nonparametric conditional density estimation -- pretty much what can be achieved using the np package. However, I need to be able to use the output of the np package in such a way that i get a continuous function as output, which can be integrated on any given interval between -Inf and Inf. This integration will of have to be across mutliple dimension since I am working with a conditional pdf. Any advise on how to accomplish this? I suspect that I need to use some kind of interpolation package to get from the output of the np package to getting a function that can be integrated, but that is exacly where I am stuck....
