Kernel Distribution

Fit a smoothed distribution based on a kernel function and evaluate the distribution

Statistics and Machine Learning Toolbox™ offers multiple ways to work with the kernel distribution.

Create a KernelDistribution object and use KernelDistribution object functions.
Use distribution-specific functions.

To learn about the kernel distribution, see Kernel Distribution.

Kernel Distribution
A kernel distribution is a nonparametric representation of the probability density function of a random variable.
Nonparametric and Empirical Probability Distributions
Estimate a probability density function or a cumulative distribution function from sample data.
