We distinguish two forms of beta coefficient: 1) ex post – beta determined by past, historical data, 2) ex ante – the estimation of beta coefficient to. the future, i.e. expected beta . 1 Size of the beta coefficient also depends on the type of company whose securities are traded, for example energetics usually has β <1 and in insurance ...
翻訳 · The coefficient of determination, R 2, is a statistical measure that shows the proportion of variation explained by the estimated regression line. Variation refers to the sum of the squared differences between the values of Y and the mean value of Y, expressed mathematically as. R 2 always takes on a value between 0 and 1.
Its interpretation is that differ- ... Coefficient of reliability, R, estimates the proportion ... 0.8 means that 80% of the total variability is true variation, while the remaining proportion (20%) is attributable to measurement error, described by Marks and colleagues  as imprecision and unreliability.

翻訳 · Algebra simplifies expressions with coefficients, which are numbers preceding variables. For example, 3 is the coefficient in 3x.Rather than using a multiplication sign between 3 and x, the number is just written in front of a variable, which means that the 3 and x are multiplied together. Instead of writing a + a + a + a, you can express it as 4a, with 4 being the coefficient.

COEFFICIENT Abstract. Conditional inference about a mean of an inverse Gaussian distribution with known coefficient of variation is discussed. For a random sample from the distribution, sufficient statistics with respect to the mean parameter include an ancillary statistic. The effects of condition-
The coefficient of variation (COV) is the ratio of the standard deviation to the mean, i.e. COV = s/ . COV is dimensionless and it is a particularly useful measure of uncertainty. A small uncertainty would typically be represented by a COV = 0.05 while considerable uncertainty would be indicated by a COV = 0.25.
