```To the Mathgroup

Do the the statistical packages in Mathematica conflict with
each others. For example, the package `Master` does not work
with the normal distribution.

Mathematica 2.0 for MS-DOS 386/7

In[1]:= <<Statistics`Master`

In[2]:= PDF[NormalDistribution[0,1],x]

PDF::shdw: Warning: Symbol PDF appears in multiple contexts
{Statistics`Common`DistributionsCommon`, Global`}; definitions in context
Statistics`Common`DistributionsCommon`

Out[2]= PDF[NormalDistribution[0, 1], x]

What did go wrong?

And here is one more example

In[1]:= !!alku.m
<<Statistics`ContinuosDistributions`
<<Statistics`NormalDistribution`

In[1]:= <<alku.m

SetDelayed::write:
Tag ChiSquareDistribution in Domain[ChiSquareDistribution[___]]
is Protected.

SetDelayed::write:
Tag ChiSquareDistribution in PDF[ChiSquareDistribution[n_], x_]
is Protected.

SetDelayed::write:
Tag ChiSquareDistribution in CDF[ChiSquareDistribution[n_], x_]
is Protected.

General::stop: Further output of SetDelayed::write
will be suppressed during this calculation.

Set::write: Tag FRatioDistribution in Domain[FRatioDistribution[___]]
is Protected.

Set::write: Tag NormalDistribution in Domain[NormalDistribution[___]]
is Protected.

Set::write: Tag NormalDistribution in
Skewness[NormalDistribution[mu_:0, sigma_:1]] is Protected.

General::stop: Further output of Set::write
will be suppressed during this calculation.

In[2]:= PDF[NormalDistribution[0,1],x]

1
Out[2]= ----------------
2
x /2
E     Sqrt[2 Pi]

It however did work.
