If a random variable follows a uniform probability distribution in some interval, then any subinterval of possible values of equal length will be equally likely. The most important probability distribution of all is the normal distribution, which is applied very often in practice and has a number ...

The cumulative distribution function F(x) of an exponential random variable is given by F(x)=P{X≤x}=∫0xλe−λy dy=1−e−λx,x≥0 The exponential distribution often arises, in practice, as being the distribution of the amount of time until some specific event occurs. For ...
system, it is very common to construct a fatigue damage spectrum by estimating the damage for an individual subsystem or component that can be modeled as a single-degree-of-freedom system subjected to base random excitation, whose natural frequency is allowed to vary as an independent variable. ...
operation GenerateRandomNumberInRange(max : Int) : Int { // Determine the number of bits needed to represent `max` and store it // in the `nBits` variable. Then generate `nBits` random bits which will // represent the generated random number. mutable bits = []; let nBits = BitSizeI...
A continuous random variable deals with measurements with an infinite number of likely outcomes. Define random variables and learn how to compute and to interpret the expected value of a continuous random variable with the probability density function. ...
Using the normal distribution is a method for answering questions about large populations. Learn about using the normal distribution and finding the Z-score, and study one- and two-sided practice problems. Related to this QuestionLet Z be a standard normal random variabl...
Random forests can be used for solving regression (numeric target variable) and classification (categorical target variable) problems. Random forests are an ensemble method, meaning they combine predictions from other models. Each of the smaller models in the random forest ensemble is a decision tree...
