Probability distribution functions (PDFs) are fundamental to data science, yet they are often misunderstood. A PDF is a mathematical function that provides the probabilities of occurrence of ...

Placing a prefix for the distribution function changes it's behavior in the following ways: dxxx(x,) returns the density or the value on the y-axis of a probability distribution for a discrete value ...

A Probability distribution is a function that represents the probability of occurrence of a random variable. Probability distributions are used in various hydrological studies, particularly in studies ...

Several probability distribution functions such as exponential distribution function have been used to represent the task arrival process and processing time of tasks for multimedia systems. These ...

Four other probability distribution functions outperformed the gamma distribution and, like the gamma distribution, also have only two unknown parameters (Tables 1, 4). Log-normal, log-logistic, and ...

Probability distribution functions (PDFs) describe the expected values of random variables drawn from a sample. The shape of the PDF explains how likely it is that an observed value might occur.

The corresponding cumulative distribution function question is, "What's the probability you'll be shorter than 5'4"?" The figure above showed two normal distributions . You can now see these are ...

The experimentally measured amplitude probability density function (APDF) of clutter reflections exhibits the larger deviations and is better fitted by APDFs such as lognormal, Weibull, K-distribution ...
