Plotkd

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

plotkd(x)

plotkd(x,'normal')
