plotdens - Draw a nonparametric density estimate

Calling Sequence

plotdens(X)
plotdens(X,h,P,K)

Parameters

Description

Draw a nonparametric density estimate. A density estimate is plotted using a kernel density estimate. A longer form plotdens(X,h,P,K) may be used where

  • h : is the kernel bandwidth,
  • P : is 1 if the density is known to be 0 for negative X,
  • K : is
  • 1 : Gaussian (the default)
  • 2 : Epanechnikov
  • 3 : Biweight
  • 4 : Triangular
  • Below the density estimate a jittered plot of the observations is shown.
