SOFTWARE BUG THAT BREAKS PREVIOUSLY WORKING FUNCTIONALITY
Regression bugs; Regression bug; Regression (programming); Regression detection; Bug regression; Software performance regression
A software regression is a type of software bug where a feature that has worked before stops working. This may happen after changes are applied to the software's source code, including the addition of new features and bug fixes.
Nonparametric regression         
  •  Example of a curve (red line) fit to a small data set (black points) with nonparametric regression using a Gaussian kernel smoother. The pink shaded area illustrates the kernel function applied to obtain an estimate of y for a given value of x. The kernel function defines the weight given to each data point in producing the estimate for a target point.
CATEGORY OF REGRESSION ANALYSIS
