How can I do? Thanks, Scout? I am not entirely sure I understand what you are trying to do. It looks to me as if you are trying to simply replace x with z when f(z) is defined. If so, then look at the following: In[1]:=<< "Statistics`" In[2]:=p = PDF[NormalDistribution[0, 1], x] Out[2]=1/(E^(x^2/2)*Sqrt[2*Pi]) In[3]:=f[z_] = p /. x -> z Out[3]=1/(E^(z^2/2)*Sqrt[2*Pi]) But if this is your goal, it seems to me it would have been simpler to define p as a function in the first place, i.e., p[x]:= PDF[NormalDistribution[0,1],x] then whenver you want to use a different variable such as z you would simply use p[z] -- To reply via email subtract one hundred and four
