Question

The quantum version of an object named for this person is defined with the symmetric logarithmic derivative. A matrix named for this person is used as the metric in information geometry, and the Jeffreys prior is proportional to the square-root of the determinant of that matrix. This person names a quantity equal to the variance of the score function, the reciprocal of which appears in the Cramér–Rao bound. The degree to which unknown parameters of a probability distribution can be determined by observations is measured by this person’s namesake (10[1])“information.” (10[1])A statistic named for this person is the ratio of variation between groups to variation within groups. This (10[1])developer of ANOVA introduced the concepts of p-value (-5[1])and hypothesis testing. For 10 points, name this British statistician and geneticist (-5[1])who names the F-test. ■END■ (0[7])
