Where,
- M̂ij = Normalised marks of the jth candidate in the “ ith” shift.
- M̅ t g = is the average marks of the top 0.1% of the candidates considering all shifts (the number of candidates will be rounded up).
- Mq g = is the sum of the mean and standard deviation marks of the candidates in the examination considering all shifts.
- M̅ti = is the average marks of the top 0.1% of the candidates in the “ith” shift (the number of candidates will be rounded up).
- Miq = is the sum of mean marks and standard deviation of the “ ith” shift.
- Mij = is the actual marks obtained by the jth candidate in the “ith” shift.
- Mq gm = is the sum of the mean marks of candidates in the shift having maximum mean and standard deviation of marks of candidates in the examination considering all shifts.
