Sven Bohm asks:
"How can I plot a propability distribution in mathematica? For example
if I have LogNormalDistribution[1.16329, 0.649846] how do I get a
plot with the frequency on the y axis?"
The following should do it....
In[1]:
<<Statistics`ContinuousDistributions`
In[2]:
f[y_] := PDF[LogNormalDistribution[mu, sig], y]
F[y_] := CDF[LogNormalDistribution[mu, sig], y]
In[3]:
mu = 1.16329; sig = 0.649846;
Plot[f[y], {y, 0.01, 10}, PlotLabel -> "Probability Density Function"]
Plot[F[y], {y, 0.01, 10}, PlotLabel -> "Distribution Function"]
