Continental Congress. Franklin returned to Philadelphia in 1775. There he served as a delegate to the Continental Congress, where he was instrumental in drafting the Declaration of Independence and the Articles of Confederation to form a new union.
In its simplest form (when r is an integer), the negative binomial distribution models the number of failures x before a specified number of successes is reached in a series of independent, identical trials. Its parameters are the probability of success in a single trial, p, and the number of successes, r. A special case of the negative binomial distribution, when r = 1, is the geometric distribution, which models the number of failures before the first success. More generally, r can take on non-integer values.
An exponential-negative binomial distribution 193 1. INTRODUCTION The exponential distribution is the ï¬rst and most popular model for fail-ure times. In recent years, many authors have proposed generalizations of the exponential distribution. The generalizations are based on aâfailure of a systemâ framework.
