A particular example of a uniform law of large numbers states the conditions under which the convergence happens uniformly in θ. If [29] [30] Θ is compact, f(x,θ) is continuous at each θ ∈ Θ for almost all xs, and measurable function of x at each θ.
For every (fixed) , is a sequence of random variables which converge to () almost surely by the strong law of large numbers. Glivenko and Cantelli strengthened this result by proving uniform convergence of F n {\displaystyle \ F_{n}\ } to F . {\displaystyle \ F~.}

Furthermore, the more often the coin is tossed, the more likely it should be that the ratio of the number of heads to the number of tails will approach unity. Modern probability theory provides a formal version of this intuitive idea, known as the law of large numbers. This law is remarkable because it is not assumed in the foundations of ...
Then (provided there is no systematic error) by the law of large numbers, the sequence X n will converge in probability to the random variable X. Predicting random number generation; Suppose that a random number generator generates a pseudorandom floating point number between 0 and 1.
Uniform convergence in probability has applications to statistics as well as machine learning as part of statistical learning theory. The law of large numbers says that, for each single event A {\displaystyle A} , its empirical frequency in a sequence of independent trials converges (with high probability) to its theoretical probability.
The law of truly large numbers (a statistical adage), attributed to Persi Diaconis and Frederick Mosteller, states that with a large enough number of independent samples, any highly implausible (i.e. unlikely in any single sample, but with constant probability strictly greater than 0 in any sample) result is likely to be observed. [1]
From the law of large numbers it follows that as N grows, the distribution of converges to = [] (the expected value of a single coin toss). Moreover, by the central limit theorem , it follows that M N {\displaystyle M_{N}} is approximately normally distributed for large N {\displaystyle N} .
