Probability Theory
Published in Hugo D. Junghenn, Principles of Analysis, 2018
Many terms in modern probability theory reflect the classical origins of the subject as well as its use in analysing real data. For example, the set Ω $ \Omega $ of a probability space (Ω,F,P) $ (\Omega ,\boldsymbol{{ \fancyscript {F}}}, P) $ is called the sample space (in practice, the set of outcomes of an experiment), and members of F $ \boldsymbol{{ \fancyscript {F}}} $ are called events (sets of outcomes). Properties holding almost everywhere are said to hold almost surely (a.s.). A real-valued (Borel) measurable function is called a random variable and may be viewed as a numerical description of an outcome of an experiment. A measurable function that takes values in Rd $ \mathbb R ^{d} $ is called a d-dimensional random variable.

A sequence of random variables {ξi} is said to converge with probability one (also, simetimes, said to converge almost surely or strongly) to a random variable ξ if P{limi→∞ξi → ξ} = 1.

A set with a non-empty interior that contains the origin is called a proper set, and a proper set that is also compact and convex is called a PC-set. In data-driven methods, a dataset is randomly split into a training set for training a model and a testing set for testing the generalisation of the trained model. In probability theory, an event is said to happen almost surely if it happens with probability 1 (or Lebesgue measure 1). A function is of class if it is continuous, strictly increasing, , and . A variable θ is said to evolve according to a bounded rate-of-variation (ROV) if for all time samples , there exists a δ such that .

From (19) and (31), on the event for all Furthermore, on the event for the random variable defined by i.e., is bounded. It is easy to see that, where stands for convergence almost surely. Using (19, 30, 32), boundedness of and Taylor series expansion, we can easily obtain the result (20) from the following expression: □

Hence, we have to exclude that there exists a function such that almost surely. implies in particular that f is continuous. Thus almost surely is equivalent to surely. Hence, being a coboundary implies that for each periodic point x of period d that which can easily be excluded numerically. The points 1/3 and 2/3 are alternating periodic points with respect to φ as well as the points 1/7, 2/7, and 4/7. Calculating the values with Maxima using double gives for the real part and for the absolute value each with 15 valid digits.
