  2. Indian National Mathematical Olympiad - Wikipedia

    en.wikipedia.org/wiki/Indian_National...

    The Indian Olympiad Qualifier in Mathematics (IOQM) is a national exam for students in grades 8-12. It's used to shortlist students for HBCSE's Mathematical Olympiad program. Students must be under 20 years old by June 30 of the IMO year and cannot have passed Class 12.

  3. DFFITS - Wikipedia

    en.wikipedia.org/wiki/DFFITS

    Thus, for low leverage points, DFFITS is expected to be small, whereas as the leverage goes to 1 the distribution of the DFFITS value widens infinitely. For a perfectly balanced experimental design (such as a factorial design or balanced partial factorial design), the leverage for each point is p/n, the number of parameters divided by the ...

    The cutoffs (minimum scores required to receive a gold, silver, or bronze medal respectively) are then chosen so that the numbers of gold, silver and bronze medals awarded are approximately in the ratios 1:2:3. Participants who do not win a medal but who score 7 points on at least one problem receive an honorable mention. [18]

  5. Bridge scoring - Wikipedia

    en.wikipedia.org/wiki/Bridge_scoring

    Note 1: Using American Contract Bridge League (ACBL) methods, scoring is one point for each pair beaten, and one-half point for each pair tied. Note 2: The rule of two matchpoints for each pair beaten is easy to apply in practice: if the board is played n times, the top result achieves 2n−2 matchpoints, the next 2n−4, down to zero. When ...

  6. Youden's J statistic - Wikipedia

    en.wikipedia.org/wiki/Youden's_J_statistic

    The index was suggested by W. J. Youden in 1950 [2] as a way of summarising the performance of a diagnostic test; however, the formula was earlier published in Science by C. S. Peirce in 1884. [3] Its value ranges from -1 through 1 (inclusive), [ 2 ] and has a zero value when a diagnostic test gives the same proportion of positive results for ...

  7. Half-power point - Wikipedia

    en.wikipedia.org/wiki/Half-power_point

    The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately −3 dB. [1] [a]In filters, optical filters, and electronic amplifiers, [2] the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency.

  8. Hand evaluation - Wikipedia

    en.wikipedia.org/wiki/Hand_evaluation

    6 card suit = 2 points; 7 card suit = 3 points ... etc. A hand comprising a 5-card suit and a 6-card suit gains points for both, i.e., 1 + 2 making 3 points in total. Other combinations are dealt with in a similar way. These distribution points (sometimes called length points) are added to the HCP to give the total point value of the hand.

  9. Cutoff frequency - Wikipedia

    en.wikipedia.org/wiki/Cutoff_frequency

    It is sometimes taken to be the point in the filter response where a transition band and passband meet, for example, as defined by a half-power point (a frequency for which the output of the circuit is approximately −3.01 dB of the nominal passband value). Alternatively, a stopband corner frequency may be specified as a point where a ...
