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.

Fit probability distributions to data

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.

This example shows how to fit a kernel probability distribution object to sample data.
Fit Kernel Distribution Using ksdensity
This example shows how to generate a kernel probability density estimate from sample data using the ksdensity function.
Fit Distributions to Grouped Data Using ksdensity
This example shows how to fit kernel distributions to grouped sample data using the ksdensity function.
