Topic: Convergence in probability


In the News (Fri 17 Feb 12)

  
  Convergence - Wikipedia, the free encyclopedia
Convergent boundary is a fault boundary defined in the specialty of Geology known as Plate techtonics.
Convergence and Unity is a coalition of the two political parties Democratic Convergence of Catalonia and the Democratic Union of Catalonia in Catalonia Spain.
CONvergence (convention) is a speculative fiction convention in Minnesota.

 Convergence of random variables - Wikipedia, the free encyclopedia
The convergence (in one of the senses presented below) of sequences of random variables to some limiting random variable is an important concept in probability theory, and its applications to statistics and stochastic processes.
It is the notion of convergence used in the central limit theorem and the (weak) law of large numbers.
Convergence in probability is the notion of convergence used in the weak law of large numbers.

Convergence to a random variable The preceding has dealt with conditions under which a random variable converges to a constant, for example, the way that a sample mean converges to the population mean.
Although convergence in rth mean and almost surely still both imply convergence in probability, it remains true, even with convergence to a random variable instead of a constant, that these are different forms of convergence.
The reason is that convergence in distribution is a property of the CDF of the random variable, not the variable itself.

 convergence
We are less familiar with an analogous statistical concept of "convergence in distribution," where the characteristic of the limit isn't a single value, but rather that the character of the sequence itself approaches some specific distribution.
Convergence in probability says that the random variable converges to a value I know.
Because they do not have to sample everywhere in the probability space, only where the variables most probably reside, these methods are not fettered by the problem of large dimensions (the Curse of Dimensionality).

Two of those were convergence in probability and >convergence with probability one.
The example in "Probability and Random Processes" by Grimmett and Stirzaker of something which converges in probability but NOT w.p.1 is: X_n = 1 with probability 1/n 0 with probability 1 - 1/n It's pretty clear that X_n -> 0 in probability.
G&S's proof is more or less: The probability that X_n is 0 for all n from m onwards is lim r-> infinity of (1-1/m)(1-1/(m+1))...(1-1/r) = lim M->infinity of (m-1 / m)(m / m+1)(m+1 / m+2)...(M / M+1) = lim M->infinity of (m-1)/(M+1) which is zero for all m.

 Convergence
The statement that an event has probability 1 is the strongest statement that we can make in probability theory.
Thus, convergence with probability 1 is the strongest form of convergence.
However, as we will see, convergence in probability is much weaker than convergence with probability 1.

 60: Probability theory and stochastic processes
Probability theory is simply enumerative combinatorial analysis when applied to finite sets; thus the techniques and results resemble those of discrete mathematics.
Probability concepts are applied across mathematics when considering random structures, and in particular lead to good algorithms in some settings even in pure mathematics.
Probability questions given a finite sample space are usually "just" a lot of counting, and so are included with combinatorics.

Convergence of Probability Measures, 2nd Edition:0471197459:Patrick Billingsley (The Univ. of Chicago, Illinois):eCampus.com
A new look at weak-convergence methods in metric spaces—from a master of probability theory In this new edition, Patrick Billingsley updates his classic work Convergence of Probability Measures to reflect developments of the past thirty years.
Assuming only standard measure-theoretic probability and metric-space topology, Convergence of Probability Measures provides statisticians and mathematicians with basic tools of probability theory as well as a springboard to the "industrial-strength" literature available today.

 Amazon.com: Probability and Measure, 3rd Edition: Books   (Site not responding. Last check: 2007-10-28)
Retaining the unique approach of the previous editions, this text interweaves material on probability and measure, so that probability problems generate an interest in measure theory and measure theory is then developed and applied to probability.
Probability and Measure provides thorough coverage of probability, measure, integration, random variables and expected values, convergence of distributions, derivatives and conditional probability, and stochastic processes.
"Probability and Measure" by P. Billingsley covers a lot of topics in probability theory, and in this sense it is a standard reference, but what I did not like much is that the concepts are somewhat scattered around the book, so one has to jump back and forth all the time.

 Effective Convergence in Probability and an Ergodic Theorem forIndividual Random Sequences
Effective Convergence in Probability and an Ergodic Theorem for Individual Random Sequences: Theory of Probability & Its Applications Vol.
An algorithmic analysis of the ergodic theorem for a measure-preserving transformation is given.
We present a formulation and a proof of the ergodic theorem for individual random sequences based on A.N. Kolmogorov's algorithmic approach to the substantiation of the theory of probability and information theory.

 Convergence Of Probability Measures; Billingsley, Patrick; Billingsley; Hardcover; World Retail Store - English Books
Asymptotic distribution theorems in probability and statistics have always depended on the classical theory of weak convergence of distribution functions in Euclidean space.
This text is about weak convergence methods in metric spaces, with applications

 Generic Uniform Convergence
This paper presents several generic uniform convergence results that include generic uniform laws of large numbers.
These results provide conditions under which pointwise convergence almost surely or in probability can be strengthened to uniform convergence.
The results are useful for establishing asymptotic properties of estimators and test statistics.

This second edition will, probably and rightly, be urged on today's research students by their predecessors, now their supervisors, who derived so much from the first edition.
As the author says, 30 years ago the book would take the aspiring researcher to the forefront.
