1. ## statistics notation help

in the chapter for normal distributions, it has a function in the formula exp[ ]. with x -mu in it. at first i thought this meant exponent, but its not. any ideas what this means?

expectation.. Exp[X-mu] will be the expectation value of X-mu..

3. i found it actually... exp(b) means e^b who would have thought? this book suuuucks

4. yeah, i found it in my notes to..

i forgot that E[] is the notation for expectation value and not exp.. so, it is just simply the exponential function..
