Continuous CDFs

Expectation

Examples

Continuous uniform distribution

PDF, CDF, notation, R code, MGF

Find the mean, variance

Special case: unif(min = 0, max = 1)

Normal distribution

PDF, notation, R code

Standard normal: Z

φ, Φ

If X ~ norm(m,s) then Z = (X-m)/s ~ norm(0,1)

MGF of Z

MGF of X

MGF of Y = a + bX

68-95-99.7 (Empirical) Rule

Example: find P(a < X < b) for something, say, IQ

Quantiles and the quantile function

Want to go in reverse: given area, find the IQ
