Graphs of probabilities of getting the best candidate (red circles) from n applications, and k/n (blue crosses) where k is the sample size. The secretary problem demonstrates a scenario involving optimal stopping theory [1] [2] that is studied extensively in the fields of applied probability, statistics, and decision theory.
A day order or good for day order (GFD) (the most common) is a market or limit order that is in force from the time the order is submitted to the end of the day's trading session. [4] For stock markets , the closing time is defined by the exchange.

Following this rule may result in a make-to-order manufacturer converting to make-to-stock. The inventory added at the aggregation point is significantly less than the inventory reduction downstream. In all stocking locations, initial inventory buffers are set which effectively create an upper limit of the inventory at that location.
Biology is the overall natural science that studies life, with the other life sciences as its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and ...
A common strategy is to grow the tree until each node contains a small number of instances then use pruning to remove nodes that do not provide additional information. [1] Pruning should reduce the size of a learning tree without reducing predictive accuracy as measured by a cross-validation set. There are many techniques for tree pruning that ...
The Paradox of Choice – Why More Is Less is a book written by American psychologist Barry Schwartz and first published in 2004 by Harper Perennial. In the book, Schwartz argues that eliminating consumer choices can greatly reduce anxiety for shoppers.
