- “Dividing the volatility, or risk, of the investment by the absolute value of its expected return determines its COV.”
With volatility in stock markets becoming something of a “new normal”, discuss the implications of using a coefficient of variation (COV), as described in the attached article: “What Does the Coefficient of Variation (COV) Tell Investors?”
- Statistical Uncertainty
Stephen Evans, professor of pharmacoepidemiology, London School of Hygiene & Tropical Medicine, said it was important not to pay too much attention to the exact percentage value of the efficacy.
“While the best estimate is 94.1% against all Covid-19 disease, the statistical uncertainty in this is such that the data are compatible with a true efficacy of about 87%,” he said. “This is, of course, still a very good efficacy. Similarly, the 100% efficacy against more severe disease is compatible with an efficacy of 90%, again, this is very good and is some evidence that severe as well as mild disease is prevented.”
