    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

    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. Shrinkflation - Wikipedia

    en.wikipedia.org/wiki/Shrinkflation

    Shrinkflation allows manufacturers and retailers to manage rising production costs while maintaining sales volume (despite receiving record profits since 2020), operating margin, and profitability, and is often used as an alternative to raising prices in line with inflation. [7] [5] Consumer protection groups are critical of the practice.

  6. Shrinkage (accounting) - Wikipedia

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

    In accounting, shrinkage or shrink occurs when a retailer has fewer items in stock than were expected by the inventory list. This can be caused by clerical error, or from goods being damaged, lost, or stolen between the point of manufacture (or purchase from a supplier) and the point of sale. [1] High shrinkage can adversely affect a retailer's ...

  7. Sales variance - Wikipedia

    en.wikipedia.org/wiki/Sales_variance

    There are two reasons actual sales can vary from planned sales: either the volume sold varied from the expected quantity, known as sales volume variance, or the price point at which units were sold differed from the expected price points, known as sales price variance. Both scenarios could also simultaneously contribute to the variance.

    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. All-commodity volume - Wikipedia

    en.wikipedia.org/wiki/All-commodity_volume

    All-commodity volume (ACV) is a weighted measure of product availability, or distribution, based on total store sales. In other words, ACV is the percentage of sales in all categories that are generated by the stores that stock a given brand (again, at least one SKU of that brand) (note: ACV can be expressed as a percentage or as a dollar value (total sales of stores carrying brand).
