  2. Least-angle regression - Wikipedia

    en.wikipedia.org/wiki/Least-angle_regression

    Standardized coefficients shown as a function of proportion of shrinkage. In statistics, least-angle regression (LARS) is an algorithm for fitting linear regression models to high-dimensional data, developed by Bradley Efron, Trevor Hastie, Iain Johnstone and Robert Tibshirani.

  3. Shrinkage (statistics) - Wikipedia

    en.wikipedia.org/wiki/Shrinkage_(statistics)

    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. [ 1 ]

  4. Estimation of covariance matrices - Wikipedia

    en.wikipedia.org/wiki/Estimation_of_covariance...

    This can be done by cross-validation, or by using an analytic estimate of the shrinkage intensity. The resulting regularized estimator (+ ()) can be shown to outperform the maximum likelihood estimator for small samples. For large samples, the shrinkage intensity will reduce to zero, hence in this case the shrinkage estimator will be identical ...

  5. Running out the clock - Wikipedia

    en.wikipedia.org/wiki/Running_out_the_clock

    In sports strategy, running out the clock (also known as running down the clock, stonewalling, killing the clock, chewing the clock, stalling, time-wasting (or timewasting) or eating clock [1]) is the practice of a winning team allowing the clock to expire through a series of preselected plays, either to preserve a lead or hasten the end of a one-sided contest.

  6. Partial least squares regression - Wikipedia

    en.wikipedia.org/wiki/Partial_least_squares...

    Partial least squares (PLS) regression is a statistical method that bears some relation to principal components regression and is a reduced rank regression [1]; instead of finding hyperplanes of maximum variance between the response and independent variables, it finds a linear regression model by projecting the predicted variables and the observable variables to a new space of maximum ...

  7. Average Run Rate method - Wikipedia

    en.wikipedia.org/wiki/Average_Run_Rate_method

    This meant that Team 2 just had to match the average run rate achieved by Team 1 in the overs it had available. For example, if Team 1 made 250 in their 50 overs, which was an ARR of 5 runs per over, and Team 2's innings was reduced to 25 overs, Team 2's new target was (5 x 25) + 1 = 126. [1] This formula could alternatively be written as:

    Inventory shrink, including retail theft, is still weighing on Target . In 2023, Target faced multiple headwinds, as tightening financial conditions dragged down its top and bottom lines.

  9. Win Shares - Wikipedia

    en.wikipedia.org/wiki/Win_Shares

    It considers statistics for baseball players, in the context of their team and in a sabermetric way, and assigns a single number to each player for his contributions for the year. A win share represents one-third of a team win, by definition. [2] If a team wins 80 games in a season, then its players will share 240 win shares.
