# Joint Distribution

## Definition of Joint Distribution

Joint Distribution: A joint distribution is a way of representing the probability of two or more events occurring simultaneously.

## What is Joint Distribution used for?

Joint Distribution is a statistical tool used to analyze the relationship between two or more random variables. It measures how one variable affects another in a given data set, and is often used to identify correlations between multiple variables. Joint Distribution provides an overall picture of the data by displaying all possible combinations of the variables and their probabilities. This makes it a useful tool for understanding the structure of complex data sets with multiple variables.

In machine learning, Joint Distribution is used to estimate the probability distribution of a specific output given certain input values. The joint probability distribution can be plotted as a surface over multiple dimensions, allowing researchers to visualize and explore different relationships between different input values and outputs. In addition, this method can be used to predict the probability of occurrence of each output from a given set of inputs. This can help researchers better understand which inputs have the highest impact on various outcomes, thereby guiding future machine learning models towards improved accuracy and performance.
