In statistics, shrinkage is the reduction in the effects of sampling variation. In regression analysis, a fitted relationship appears to perform less well on a new data set than on the data set used for fitting. In particular the value of the coefficient of determination 'shrinks'. This idea is complementary to overfitting … Prikaži več Many standard estimators can be improved, in terms of mean squared error (MSE), by shrinking them towards zero (or any other fixed constant value). In other words, the improvement in the estimate from the … Prikaži več • Additive smoothing • Boosting (machine learning) • Chapman estimator • Principal component regression Prikaži več A well-known example arises in the estimation of the population variance by sample variance. For a sample size of n, the use of a divisor … Prikaži več Types of regression that involve shrinkage estimates include ridge regression, where coefficients derived from a regular least squares regression are brought closer to zero by multiplying by a constant (the shrinkage factor), and lasso regression, where coefficients … Prikaži več • Hausser, Jean.
