(2011) Science 334(6062):1518-1524], which proposed an alternative definition of equitability and introduced a new statistic, the "maximal information coefficient" (MIC), said to satisfy equitability in contradistinction to mutual information. The benchmark for the ratio’s calculation is the S&P 500 index. I have also seen a definition of Information Ratio that doesn't compare returns to a benchmark. The Respiratory Quotient (RQ), also known as respiratory coefficient, is a number that is quite useful to calculate the basal metabolic rate (BMR). Interpreting the Intercept. A mutual fund is a pool of money collected from many investors for the purpose of investing in stocks, bonds, or other securities.
