In the graph above, the two shaded areas are equidistant from the null hypothesis value and each area has a probability of 0.025, for a total of 0.05. In statistics, we call these shaded areas thecritical regionfor a two-tailed test. If the population mean is 260,...
These statistical tests are reported as “significant” if they pass Holm–Bonferroni correction for the 12 comparisons (alpha = 0.05) (i.e., the 12 uncorrected p-values are ordered and the lowest p-value is significant if it is below 0.05/12 = 0.0042, the second lowest is ...
For Example 1, =KALPHA(I4:L11) takes the value .169204, which is the same value as that found in cell U19. The array formula =KTRANS(B4:F13) returns the array in range I4:L11. The formula =KALPHA(KTRANS(B4:F13)) also outputs the Krippendorff alpha value of .169204. Exam...
(Fig.3a). Additionally, hills are removed whose elution profiles do not conform to minimal criteria, like minimal length and the existence of local minima. To efficiently connect hills, we compute summary statistics such as weighted average m/z value and a bootstrap estimate of its precision. ...
There's a famous quotation in statistics, made in 1976 by British statistician George Box. "Essentially, all models are wrong, but some are useful." That's how I view DG investing. It's not right about everything...

Find the critical value z_{alpha / 2} that corresponds to alpha = 0.04. Find the critical value z_{\alpha/2} that corresponds to α = 0.12. Find the critical value z a l p h a / 2 that corresponds to alpha = 0.10. Find the value of alpha in the relation Cov (2X, -3Y...
p-value = 0.0136 Though the mean difference in log returns is not statistically different from 0, relative performance is not a random walk. The relative returns of PRF and the replicating portfolio are autocorrelated, as is evident in the chart above. ...
