# Uniform Distribution with support?

Posted 9 years ago
 Hey, i got a small issue and im pretty sure that the community will easely solve this. The Problem: 1. we have Epsilon which is uniformely distributed with support {epsilonL , epsilonH} and epsilonL = - epsilonH and mean(epsilon) = 0 with g(epsilon) the density function. 2 My Code: \[Epsilon] = UniformDistribution[{Subscript[\[Epsilon], L], Subscript[\[Epsilon], H]}] g[\[Epsilon]] = PDF[\[Epsilon], x]  The Problem is that Mathematica has an issue to execute this and i think its the subscripts that create this issue. I am new to Mathematica and i would be happy if someone can help me. What are my mistakes and could somebody explain me in other words what the message Hold{} means? i read the documentation about that but i am not sure if i got it completely. Thx in advance

 Using lists handles multiple observations. Look in the online documentation about lists, set ("="), set delayed (":="), and Solve. If you have a specific example about the use of Solve (including in code you've attempted), then I think the Community could give you a lot of assistance. Looking at "Core Language & Structure" in the Documentation Center is also highly recommended.

 hey Jim Baldwin,ok ty for your reply. I got some further questions to your answer.Considering the subscript, what about time indices. Lets say we have xt and xt+1 . Are subscripts not fine for time indices? How would you handle a model with more periods when you cant use subscripts?The other question is related to the ":=" (delayed) . How can i use this kind of a function in SOLVE ? Because to do Solve for equations and/or in-equations you need to have equations of the form of "==" ">""<" etc but not ":=" . How can i Use this density function g[epsilon_] with Solve?

 My recommendation is to avoid subscripts (now and maybe forever). If I understand what you want, the code can be written as: \[Epsilon]L = -5; \[Epsilon]H = -\[Epsilon]L; \[Epsilon] = UniformDistribution[{\[Epsilon]L, \[Epsilon]H}] g[x_] := PDF[\[Epsilon], x] and  g[z] g[3.5] g[50] results in
