Hi, I like to generate two normal densities such that the overlapping area between them is 0.35. Is there any code/package available in R to do that??

Hi, I have a vector or random variables and I'm estimating the density using "bkde" function in the KernSmooth package. The out put contains two vectors (x and y), and the R documentation calls y as the density estimates, but my y-values are not exact density etstimates (since these are numbers larger than 1)! what is y here? Is it possible to get the true estimated density at each

...;) abline(0.07,0.01) you can see that the curves intersects at 3 points. My question is how do I mark the point of the intersection? I like to mark it as (x1,y1) as the first point of intersection and so on. or I can just mark the x-coordinate of the 1st intersection as x1 on the x-axis.

Hi, I posted this message earlier in "Rmetrics" and I don't know whether I posted in the wrong place, so I'm posting it again in Rhelp. I have a function in x and y and let's call it f(x,y). I need to get the Hessian matrix. i.e I need (d^2f/dx^2), (d^2f/dxdy), (d^2f/dydx), (d^2f/dy^2).I can get these using the D function. now I need to evaluste the hessian matrix for

...sity. Then I calculated the Kullback leibler divergence meassure between a distribution and the each of the estimated densities, but the asnwers are different. Is there any difference between the kde2d and sm.density estimates? if there is a difference, then which is the best estimate?

...x1=seq(-5,5,length=100) d3=dunif(x1,-3,3) y1=cbind(d1,d3) kl1=KLdiv(y1) Notice that kl1 and kl are not the same. the documentation for the package doesn't mention to evaluate the densities at the same points. which one is correct? do I need to evaluate them at the same point or not?
