Poisson distribution - Wikipedia, the free encyclopedia

by YukuanMark
In probability theory and statistics, the Poisson distribution is a discrete probability distribution. It expresses the probability of a number of events occurring in a fixed period of time if these events occur with a known average rate, and are independ

Poisson Distribution (for a newbie)

I am simulating an event where users come into the pool randomly starting at time T=0, i.e. For Example, 2 users came at T= 0 into the the pool, 3 users came at T= 1 into the the pool, 5 users came at T=2 ,..........,54 users came at T=45 etc. As cumulati

上面這種機率分布稱為二項分布。一般的二項分布是這樣的: 假設某事件的發生率為 p,而試驗做了 n 次。則 n 次中,某事件發生 x 次的機率為

本文的目的有二:一來淺介訊息理論,二來藉訊息理論之介紹說明機率論的方法。 首先,我們回憶一下機率的基本概念。

西元1827年,英國植物學家勞伯‧布朗 (Robert Brown) 利用一般的顯微鏡觀察懸浮於水中的花粉粒時,發現這些花粉粒會做連續快速而不規則的隨機移動,這種移動稱為布朗運動 (Brownian motion)。

Poisson 分布

by YukuanMark
二項分布是離散型機率模型中最有名的一個,其次是 Poisson 分布,它可以看成為二項分布的一種極限情形。

Random Number Generator Source Code

by YukuanMark
This is an ANSI C library for multi-stream random number generation. The use of this library is recommended as a replacement for the ANSI C rand() and srand() functions, particularly in simulation applications where the statistical 'goodness' of the rando

Boing Boing: Psychology of bad probability estimation: why lottos and terrorists matter

by multilinko (via)
Here's the audio from a South By Southwest 2006 presentation by Harvard's Daniel Gilbert on the psychology of probability estimation. This is important stuff -- it explains why we're socially willing to commit nigh-infinite social resources to fighting terrorism, though statistically, terrorist attacks almost never happen; though we barely lift a finger to help save people from routine traffic accidents, backyard pool drownings, and asthma, which mow down our neighbors by the thousands. It explains why people buy lottery tickets. It explains a great deal about many kinds of human activity.
