PDFSCATTER Scatter plot with superimposed pdf plot
CALLS
pdfscatter(p,C,vars,etiq)
INPUTS
p: data matrix (RxQ)
C: width factor (sigma value)
etiq: cell array with labels corresponding to the variables of p
vars: index vector with the variables (rows) of p to be displayed
Description
PDFSCATTER obtains a scatter plot with a superimposed probability
density plot. This allows to account for cases in which multiple
instances of points appear in p with the same (or very similar) coordinates.
The density plot gives a visual cue of the real trends in the
distribution of the data points of p
