Not only … Nettet13. mai 2024 · You should italicize r when reporting its value. You shouldn’t include a leading zero (a zero before the decimal point) since the Pearson correlation coefficient can’t be greater than one or less than negative one. You should provide two significant digits after the decimal point.

For instance, f ( x) = 2 x x + 1 's limiting value is 2 at ∞ as we can't determine the value of f ( x) at x = ∞.
Nettet29. des. 2024 · A fund with a low R-squared, at 70% or less, indicates that the security does not generally follow the movements of the index. A higher R-squared value indicates a more useful beta value. For example, if a stock or fund has an R-squared value close to 100%, but has a beta below 1, it most likely offers higher risk-adjusted returns.
