Class Outline
Compare and Contrast with discrete random variable
- From Discrete Uniform DU(K) to Uniform, U(0,1)
- pmf vs pdf
- Relation between the distribution function F(x) and pdf f(x) of a continous random variable
F′(x)=f(x). - pdf is not a probability but a funciton/tool for computing probability. Specifically,
f(x)≠P(X=x)
and
P(a≤X≤b)=∫baf(x) dx. - Uniform U(0,1)
- Exponential random variable $Exp(\lambda)$
- Normal random variable $N(\mu, \sigma^2).$ (if time permits)
