Credibility+Intervals

Credibility Intervals (Estimation) (GWU EMSE-271)
Index | Topics (Logical Lectures) | Lectures | Problems | Readings | References | Concepts

Credibility intervals indicate the probability that the random interval contains the value X with the stated probability; the probability between the upper and lower bounds defined by percentiles.

Placeholder: Need to add graphs and other details.

LB = {Distribution}INV (alpha, xBar s) ==> LB = NormInv (alpha, xBar s) UB = {Distribution}INV (alpha, xBar s) ==> LB = NormInv (1-alpha, xBar s)

Academic Correctness wording: "A 90% credibility interval for the (cadence) is also a random interval with a 90% random interval with a 90% probability of contain{ing} the value of X. The calcuated interval (above) is a realization of that interval and Pr(X member of [LB,UB]) is approximately 90%." - 2005 Solution
