Review of Probability Theory - Stanford University
cs229.stanford.edu2.3 Probability density functions For some continuous random variables, the cumulative distribution function F X(x) is differentiable everywhere. In these cases, we define the Probability Density Function or PDF as the derivative of the CDF, i.e., f X(x) , dF X(x) dx: (2)

Standard deviation is defined in terms of the PDF as standard deviation σμ()()x 2 fxdx ∞ −∞ == −∫.In an ideal situation in which f(x) exactly represents the population, σ is the standard deviation of the entire population.

PROBABILITY AND STATISTICS FOR ECONOMISTS
ssc.wisc.eduProbability and Statistics for Economists (this volume) 2. Econometrics (the next volume) The textbooks are written as an integrated series, but either can be used as a stand-alone course textbook. This first volume covers intermediate-level mathematical statistics. It is a gentle yet a rigorous treat-ment using calculus but not measure theory.
Grinstead and Snell’s Introduction to Probability
math.dartmouth.edube e ective 30 percent of the time it is used, we might assign a probability .3 that the drug is e ective the next time it is used and .7 that it is not e ective. This last example illustrates the intuitive frequency concept of probability. That is, if we have a probability p that an experiment will result in outcome A, then if we repeat this
