ksdensity uses a boundary correction method when you specify either positive or bounded support. The default boundary correction method is log transformation. When ksdensity transforms the support back, it introduces the 1/x term in the kernel density estimator. Therefore, the estimate has a peak near x = 0. On the other hand, the reflection ...

By default, ksdensity uses a normal kernel smoothing function and chooses an optimal bandwidth for estimating normal densities, unless you specify otherwise. Step 3. Plot the kernel probability density estimate. Plot the kernel probability density estimate to visualize the MPG distribution.

3.5.3.7.8 Ksdensity. Definition: y=ksdensity(x, vX, w) returns the kernel density at x for a given vector vX with a bandwidth w, where an optimal w can be determined by the estimation function kernelwidth. where n is the size of vector vX, is the ith element in vector vX.. Parameters: (input, double) The value to be evaluated for density (input, vector) ...

I am working with a strictly positive observation vector (they are a distance measure). I use ksdensity with this vector to get a feeling of the density function and surprisingly it includes negative values. Meaning that there is a positive probability to observe an all negative values interval.
