In association football and other sports with a goalkeeper, the goalkeeper may be said to "keep a clean sheet" if they prevent their opponents from scoring during an entire match. Because football is a relatively low-scoring game, it is common for one team, or even both teams, to score no goals. [ 3 ]
The change in a Fisher index from one period to the next is the geometric mean of the changes in Laspeyres' and Paasche's indices between those periods, and these are chained together to make comparisons over many periods: = This is also called Fisher's "ideal" price index.
To use column-major order in a row-major environment, or vice versa, for whatever reason, one workaround is to assign non-conventional roles to the indexes (using the first index for the column and the second index for the row), and another is to bypass language syntax by explicitly computing positions in a one-dimensional array.
Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).
For example, consider a supermarket with 1000 products and two customers. The basket of the first customer contains salt and pepper and the basket of the second contains salt and sugar. In this scenario, the similarity between the two baskets as measured by the Jaccard index would be 1/3, but the similarity becomes 0.998 using the SMC.
Example: The matching distance between = + + and = ′ + ′ is given by (,) = {(, ′), (, ′), (,)} = The core of the definition of matching distance is the observation that the information contained in a size function can be combinatorially stored in a formal series of lines and points of the plane, called respectively cornerlines and ...
Dealt two cards whose values are neither the same nor adjacent to each other, the player bets on whether the value of the third card will fall between the value of the first two. Red dog , also known as Yablon and Scottish Foghorn, is a game of chance played with cards , in which two cards are dealt and a player bets on whether the rank of a ...
The index terms were mostly assigned by experts but author keywords are also common. The process of indexing begins with any analysis of the subject of the document. The indexer must then identify terms which appropriately identify the subject either by extracting words directly from the document or assigning words from a controlled vocabulary ...
