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 (10[1])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. (10[1])The degree to which unknown parameters of a probability distribution can be determined by observations is measured by this person’s namesake “information.” A statistic named for this person is the ratio of variation between groups to variation within groups. This developer of ANOVA introduced the concepts of p-value and hypothesis testing. For 10 points, name this British statistician and geneticist who names the F-test. ■END■ (0[2])
