y = pdf(name,x,A) returns the probability density function (pdf) for the one-parameter distribution family specified by name and the distribution parameter A, evaluated at the values in x. y = pdf(name,x,A,B) returns the pdf for the two-parameter distribution family specified by name an...
probability density function (pdf) A function that assigns probabilities to random variables in a continuous parameter space. A function that assigns probabilities on a discrete parameter space is called a probability mass function, but many use pdf for both types of spaces. In both cases, the fu...
y= wblpdf(x)returns the probability density function (pdf) of the Weibull distribution with unit parameters, evaluated at the values inx. example y= wblpdf(x,a)returns the pdf of the Weibull distribution with scale parameteraand unit shape, evaluated at the values inx. This is equivalent to...
This MATLAB function returns the probability density function (pdf) of the standard exponential distribution, evaluated at the values in x.

1. Cumulative probability density functions return probabilities for ranges of outcomes. Two such types of probabilities are statistical significanceand (1 -β) orpower. 2. Inverse cumulative probability density functions return ranges of outcomes for (chosen) probabilities. Like so, they're used for...
A theory based on the probability density function of velocity difference, derived from the Navier-Stokes equations, is presented. The formally exact derivation leads to a pressure term and a dissipative term that need to be modeled. The asymptotic expression of the pressure term for large ...
In short, probability density functions can find non-zero likelihoods for a continuous random variable X falling within the interval [a, b]. Or, in statistical notation: P (A < X < B). Statisticiansrefer to the mean of a probability density function as its expected value. Learn more abou...
A cumulative distribution function is another type of function that describes a continuous probability distribution. Example: Probability density functionThe probability density function of the normal distribution of egg weight is given by the formula: Where: is the probability density of egg weight is ...
Perhaps the most common probability distribution is the normal distribution orbell curvealthough several distributions are commonly used. The data-generating process of some phenomenon will typically dictate its probability distribution. This process is referred to as the probability density function. ...
