DISTRIBUSI INVERS GAMMA PADA INFERENSI BAYESIAN

One of the methods which can be used in statistical inferencesxa0 is Bayesian inference. It is combine sample distribution and prior distribution, that can be resulted posterior distribution. In this article, sample distribution use univariate normal distribution. If prior distribution for variance with known mean is gamma inverse distribution, then posterior distribution is formed gamma inverse distribution. If Prior distribution use non-informative prior, then have the posterior distribution, by thexa0 marginal distribution of mean and varian. Also posterior distribution formed by gamma inverse distribution. Keywords : Gamma Inverse Distribution, Posterior Distribution, Non-Informatif Prior

PENENTUAN MODEL ANTRIAN BUS ANTAR KOTA DI TERMINAL MANGKANG

In daily activities, we often face in a situation of queueing. The Queue is dull. Most people have experienced in a queue situation or a waiting situation. It xa0is xa0a part of the state that occurs in a series of operations that are random in a service facility. The Queue can be found easily in a human life, for example bus queue in Terminal Mangkang. It means that a bus wait to be dispatched and from the bus that will go to the service station. Therefore make an arrival and departure of buses not on schedule which resulted in the accumulation of customers in the terminal. To analyze the extent of the effectiveness of terminal Mangkang particularly inter-city terminal Queue theory it is used in the service system in the terminal. Keywords : Queue, Terminal Mangkang
