Topic: Convergence in distribution

	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.
		Convergence in probability is, indeed, the (pointwise) convergence of probabilities.
		Convergence in probability is the notion of convergence used in the weak law of large numbers.

	Poisson distribution - Wikipedia, the free encyclopedia
		The distribution of visual receptor cells in the retina of the human eye.
		For temporally distributed events, the Poisson distribution is the probability distribution of the number of events that would occur within a preset time, the Erlang distribution is the probability distribution of the amount of time until the nth event.
		Skellam distribution, the distribution of the difference of two Poisson variates, not necessarily from the same parent distribution.

		The fact is that for Y constant convergence in distribution and in probability are the same.
		If is an (ergodic) Markov chain with stationary transitions and the stationary initial distribution of W has density f then you can get random variables which have the marginal density f by starting off the Markov chain and letting it run for a long time.

	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 distribution says that they behave the same way (but aren't the same value).
		Still other examples of convergence in distribution are the extreme value distributions.

	Lemmata
		This condition is also called `weak convergence of the distribution functions'.
		In general, convergence in probability implies convergence in distribution.
		We finish this section by a Lemma on multivariate normal distributions which states that a linear transform of a multivariate normal distribution is multivariate normal again.

		Intuitively, they all express the fact that any sum of many (A neutral or uncommitted person (especially in politics)) independent identically distributed (A variable quantity that is random) random variables will tend to be distributed according to a particular "attractor distribution".
		Since many real processes yield distributions with finite (The second moment around the mean; the expected value of the square of the deviations of a random variable from its mean value) variance, this explains the ubiquity of the normal distribution.
		But, this limit is just the characteristic function of a standard normal distribution, N(0,1), and the central limit theorem follows from the Lévy continuity theorem, which confirms that the (The act of converging (coming closer)) convergence of characteristic functions implies convergence in distribution.

	Random variable
		The probability distribution of random variable is often characterised by a small number of parameters, which also have a practical interpretation.
		Much of mathematical statistics consists in proving convergence results for certain sequences of random variables; see for instance the law of large numbers and the central limit theorem.
		These are explained in the article on convergence of random variables.

		Pictures of a distribution being "smoothed out" by summation (showing original distribution and three subsequent convolutions):
		Well, the logarithm of a product is simply the sum of the logs of the factors, so the log of a product of random variables tends to have a normal distribution, which makes the product itself have a log-normal distribution.
		Many physical quantities (especially mass or length, which are a matter of scale and cannot be negative) are the product of different random factors, so they follow a log-normal distribution.

	DP0317 -- Convergence as distribution dynamics (with or without growth) (Site not responding. Last check: 2007-10-21)
		Convergence concerns the poor catching up with the rich---if not instantaneously, then at least having a tendency to do so.
		When poor and rich here refer to entire economies, then whether convergence occurs is traditionally viewed as just a side consequence of a more central question, namely that concerning the nature of economic growth.
		When convergence is made central and thus investigated, new theoretical issues and empirical insights emerge: this paper provides a brief overview of what those lessons are, and conjectures what next might be learnt.

		We show that these imply the validity of Doeblin's condition, which in turn ensures the convergence in distribution of the process to an invariant probability measure with a geometric rate.
		Furthermore, it is shown that the process is positive Harris recurrent, which enables us to use statistical devices to measure the centrality and variability of the invariant probability measure.

		The last method of distribution theory that I will review is that of Monte Carlo simulation.
		To compute something like P(T > t) for some specific value of t we appeal to the limiting relative frequency interpretation of probability: P(T>t) is the limit of the proportion of trials in a long sequence of trials in which Toccurs.
		This is almost the technique we used above for the exponential distribution.

		, converges weakly to a stationary Gaussian diffusion, and the variance of the stationary measure is taken to be a measure of the rate of convergence.
		223--244], the rate of convergence literature is essentially confined to the case where the limit point is not on a constraint boundary.
		In particular, the stability methods which are used to prove tightness of the normalized iterates cannot be carried over in general, and there is the problem of proving tightness of the normalized process and characterizing the limit process.

	Income Distribution and Convergence in the Transition Process
		The aim of this study is to clarify, whether and where the widespread opinion that systemic change from socialism to capitalism went along with dramatically rising inequality is true and how income distribution does affect the overall growth performance of transition countries.
		The findings are analysed against the background of convergence or divergence respectively vis-à-vis the European Union (EU) level of income and income distribution.
		For the Czech Republic, Hungary and Poland it can be shown that income distribution remained relatively stable before and throughout the transition period on the basis of so far unpublished data from the Luxemburg Income Study database.
