Mathematical Notation

This manual and the Statistics Toolbox functions use the following mathematical notation conventions.


Parameters in a linear model.
E(x)
Expected value of x.   


f(x|a,b)
Probability density function. x is the independent variable; a and b are fixed parameters.
F(x|a,b)
Cumulative distribution function.
I([a, b]) or I[ab]
Indicator function. In this example the function takes the value 1 on the closed interval from a to b and is 0 elsewhere.
p and q
p is the probability of some event.
q is the probability of ~p, so q = 1-p.
