In the winter (like now), they are the same as Halifax, NS and as noted above are 1 hour ahead of NYC... BUT. in the spring and summer (after the spring forward time change) the DR is the same as NYC. Until the fall back time change in the Fall when they once again are the same as Halifax, NS and one hour earlier than NYC. Etc., etc., etc.
The Sortino ratio, named after Frank A. Sortino, measures the risk-adjusted return of an individual asset or a portfolio, as do the Sharpe and Treynor ratios. However, it only concerns itself with returns that fall below a user-specific minimum or required rate of return (minimum accepted return, or MAR).
Full-text (PDF) | The relative risk (RR) and the odds ratio (OR) are the two most widely used measures of association in epidemiology. The direct computation of relative risks is feasible if meaningful prevalences or incidences are available. Cross-sectional data may serve to calculate relative risks from prevalences. Cohort study designs allow for the direct calculation of relative risks from incidences. The situation is more complicated for casecontrol studies.
