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)

by YukuanMark
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

機率學的世界

by YukuanMark
一般的機率教科書,往往偏重理論公式的推導,使學生與讀者不知道如何化理論為實用。《機率學的世界》雖然在性質上屬於教科書,但是不同之處就在於,書裡儘量減少公式推導,而著重在舉

Not to be Fooled by Randomness

by YukuanBlog
最近抱讀了一些機率的書,突然發現這門學問還滿有趣的。除了有趣,一些基本的機率分配及常見的隨機過程都非常實用。在複習的過程,當然也要稍微作個紀錄:

隨機的致富陷阱

by YukuanMark
本書談的主題是明明靠運氣才完成的事,卻以非運氣(也就是需要靠人的技巧)的假面貌出現,或者被認為和運氣無關,以及推而廣之,明明是隨機現象,卻以非隨機(也就是早已決定好)的假

二項分布與大數法則

by YukuanMark
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

機率與訊息

by YukuanMark
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。

漫談布朗運動

by YukuanMark
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)。

馬可夫鏈的簡介

by YukuanMark
「不是互相獨立」也就是說互相關聯的意思,但是要樣相關呢?如何在相關中作一些簡單的分類呢?馬可夫鏈就是要描述在「相關」這個概念中最簡單的一種。

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。

機率一講

by YukuanMark
機率論的一個發源地是記述統計學;明瞭記述統計學的概念,對於機率論的學習,大有助益!

看漫畫,學統計

by YukuanMark
想速成統計判斷力,最好的方法就是靠《看漫畫,學統計》帶你上路,讓你輕鬆跨入統計學之門。

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.
