... which gives the probability of y successes out of n independent trials, where the probability of success on any one trial is p (0 < p < 1). If n is large this becomes difficult to compute. However, we can use the Central Limit Theorem (CLT) to approximate the r.v. Y with a normal r.v. Y* where Y and ...

A common error is to treat disjoint events as if they were independent, and apply the Multiplication Rule for independent events—don’t ...

... Plotting the probabilities of D conditional on exposure level X (at each level x determined) on a graph produces a straight line with intercept = a and slope = b (changes in P for each unit of x). The intercept (a) illustrates the risk of D as a probability when exposure = 0. The slope of the line i ...
