We derive a new computationally efficient formula for the probability mass function of the number of renewals by a given time. An R package coga provides efficient C++ based implementations of the discussed methods and are available in CRAN....
We prove that the distribution function exists and is continuously differentiable. We also give an explicit formula for its derivative (to be referred to as the distribution density) and establish an asymptotic formula for $\\Phi_n(Q;I)$ with upper and lower estimates for the error term in ...
The “normal curve” results from plotting f(x)f(x) -probability density- for a number of xx values. Its horizontal position is set by μμ, its width and height by σσ. The figure below gives some examples.As with all probability density functions, the formula does not return probabili...
Let's say we want to generate a random number that is uniformly distributed over an interval, say, (1,7). Back in the old days, we would have to do this with a formula. Stata 14 introduces two new functions for uniform random numbers:runiform(a,b)andruniformint(a,b).runiform(a,b...
𝑥1, 𝑥2 to calculate p(𝑥1 ≤ X ≤ 𝑥2) p(X ≤ 𝑥1), p(X ≤ 𝑥2) to calculate 𝑥1, 𝑥2, and p(𝑥1 ≤ X ≤ 𝑥2) What is a probability density function (PDF)? The Probability Density Function (PDF), indicated as f(x), is relevant to a continuous rand...
is the distribution function of a standard normal random variable (see above). The lecture entitledNormal distribution valuesprovides a proof of this formula and discusses it in detail. Density plots This section shows the plots of the densities of some normal random variables. These plots help us...
The probability density function for the normal distribution is given by: In the formula, μ (mu) is the population mean, σ (sigma) is the population standard deviation, and π (pi) is a mathematical constant approximately equal to 3.14159. The PDF shows that the normal distribution is ...
The density generators are • Normal: g(u)=(2π)−1/2exp(−u/2); • Cauchy: g(u) = [π(1+u)]−1; • Student-t: g(u) = νν/2B(1/2,ν/2)−1(ν+u)−(ν+1)/2, where ν > 0 and B(⋅,⋅) is the beta function; • Generalized Student-t: g...
