Kernel density estimation

Kernel-density-estimation

Kernel Density Estimation (KDE) is a non-parametric technique used to estimate the probability density function of a random variable. Unlike histograms, which can be limited by bin sizes and can produce jagged representations, KDE provides a smooth curve that reflects the underlying distribution of the data. By placing a kernel function, typically Gaussian, at each data point and summing their contributions, KDE generates a continuous estimate of the density. This method is particularly useful for visualizing data distributions and uncovering patterns, making it a valuable tool in statistics and data analysis.
