Lecture 7: Poisson Distribution - Physics & Astronomy
2 February 2011 Physics 3719 Lecture 7 The 3 (most?) Important Probability Distributions Binomial: Result of experiment can be described as the yes/no or success/failure outcome of a trial The probability of obtaining success is known Poisson: Predicts outcome of “counting experiments” where the expected number of counts is small
13 Poisson’s equation
Poisson’s equation and conservative forces In physics Poisson's equation is used to describe the scalar potential of a conservative force In general V = f where V is the scalar potential of the force, or the potential energy a particle would have at that point, and f is a source term Examples of conservative forces include Newton's Law of
Poisson Statistics - Department of Physics and Astronomy
Poisson distribution applies to these measurements and is useful for determining the probability of detecting a single event or more than one event in the same period The Poisson distribution is a special case of the binomial distribution, similar to the Gaussian distribution being a special case
Physics 185 Properties of the Poisson Bracket operation
Physics 185 Properties of the Poisson Bracket operation This handout reproduces and clari es my lecture of March 2 about Poisson brackets Chapter 13 and previous lectures show that Hamilton’s equations give the time derivatives for
Poisson Statistics - 157physicsucdavisedu
Jul 08, 2004 · Poisson Statistics MIT Department of Physics (Dated: July 8, 2004) In this experiment you will explore the statistics of random, independent events in physical mea surements The random events used in this study will be pulses from a scintillation detector exposed to gamma rays from a radioactive source
Lecture 8: Gaussian Distribution - Physics & Astronomy
7 February 2011 Physics 3719 Lecture 8 4 Example of Poisson Distribution Poisson distributed data can take on discrete integer values n must be an integer need not be
Lecture 5: The Poisson distribution
The Poisson distribution is a discrete probability distribution for the counts of events that occur randomly in a given interval of time (or space) If we let X= The number of events in a given interval
Measurement Uncertainties and Errors - Instructorphysicslsa
The Poisson distribution is appropriate for random processes that have a small probability of happening A good example is the radioactive decay of a nucleus If the lifetime is ~years and your measure-ment takes ~1 minute, then the probability that the nucleus will decay during your measurement is very small and the Poisson distribution "works"
