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.
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]

The examination paper comprises 30 problems to be solved over 3 Hours. The composition of the paper is 2 marker, 3 marker, and 5 marker problems. Stage 2 or Regional Mathematical Olympiad: The RMO is held between late October and early November across the country. The examination paper comprises six problems to be solved over 3 hours.
Another approach to agreement (useful when there are only two raters and the scale is continuous) is to calculate the differences between each pair of the two raters' observations. The mean of these differences is termed bias and the reference interval (mean ± 1.96 × standard deviation ) is termed limits of agreement .
The Mahalanobis distance is a measure of the distance between a point and a distribution, introduced by P. C. Mahalanobis in 1936. [1] The mathematical details of Mahalanobis distance first appeared in the Journal of The Asiatic Society of Bengal in 1936. [2]
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 ...
Youden's index is often used in conjunction with receiver operating characteristic (ROC) analysis. [4] The index is defined for all points of an ROC curve, and the maximum value of the index may be used as a criterion for selecting the optimum cut-off point when a diagnostic test gives a numeric rather than a dichotomous result.
