Purpose
Kernel density plot.
Synopsis
- plotkd(x,distname,kernel,userw,translate)
Description
Provides a kernel density plot of the input x and an overlay.
Inputs
- x = matrix (column vector) in which the sample data is stored.
- distname = string, optional distribution name to assume as the parent distribution for the sample. Default value is 'normal'.
- kernel = Integer between 1 and 7 indicating which kernel to use.
- 1 - Bivwight
- 2 - Cosine
- 3 - Epanechnikov {default}
- 4 - Gaussian
- 5 - Parzen
- 6 - Triangle
- userw = scalar, the optional window width to use in the kernel calculation. If not specified, then the optimal window width is used according to the calculation:
- '''''''''' translate = scalar, axis translation.
Examples
