A case study focuses on a single individual, a small group of people, or occasionally a single event. You'll be conducting qualitative research to find specific details and descriptions of how your subject is affected. 1  For example, a medical case study might study how a single patient is affected by an injury.ou may be asked to prove that the case study does no harm to its participants. 1  Follow this step even if you are conducting a retrospective case study. 2  In some cases, publishing a new interpretation can cause harm to the participants in the original study.

The incremental capital output ratio (ICOR) is defined as the ratio between investment in some previous period(s) and the growth in output in the subsequent period.Needless to say, ICOR calculation is based on constant price data.ormula or Equation Note.

The ratio measures the excess return (or risk premium) per unit of deviation in an investment asset or a trading strategy, typically referred to as risk (and is a deviation risk measure), named after William F. Sharpe. To this day, the Sharpe ratio is still found as a prime metric for any alternative investment.his ratio is just the Sharpe ratio, only using minimum acceptable return instead of the risk-free rate in the numerator, and using standard deviation of returns instead of standard deviation of excess returns in the denominator. In 1966, William F. Sharpe developed what is now known as the Sharpe ratio.
