ProbDistPlotPmfs
[this page]
Function Description
Returns a plot of the probability mass functions of several
probability distributions simultaneously, with the distribution names given by DistributionNames
and with parameter values (for each distribution) given in ParamValues (with
their order matching the parameter names listed by MnProbDistParamNames).
The first set of elements of ParamValues refer to the first
distribution, the next set to the second distribution etc. If the distributions
being analysed have different numbers of parameters then you should work out
the largest number of parameters any of them has and pad out the others so that
all sets of elements of ParamValues have the same size. More precisely,
returns a string which is the (temporary) code for a SmartChart that plots such
information.
To identify whether a given distribution is continuous (so
has a probability density
function) or discrete (so has a probability mass function)
see MnProbDistIsCts.
Probability distributions currently recognised by the website may be listed
using MnRecognisedProbDists.
For further details on how to use the ChartFormat
parameter to format a chart see using the ChartFormat
parameter.
