Thus, to recap, our analysis scheme consisted of choosing the appropriate ranking metric (or statistic), running the three enrichment techniques, and then focusing on the gene set obtained from the absolute enrichment analysis (since it captured the most differentially regulated gene set).
In a receiver operator curved analysis (n = 930) of the combined 20 SNP model, we found the area under the curve (AUC or C statistic) for run 1, run 2 and run 1+2 was 0.82, 0.75 and 0.77 respectively.
A value of the test statistic of the runs test greater than the critical value at a particular level of significance indicates non-randomness in the daily returns under analysis and suggests that the Indian GETF market is not weak-form efficient.
To check for the amount of burn-in, run convergence, and that the effective sample size exceed 200 for each statistic, each run was assessed graphically in Tracer v. 1.4.1 [ 76].
It also provided a reliable statistic of run error rate.
We then performed the outlier detection on all data sets, using the DFBETA statistic, and ran the MCMC for 50 simulated data sets for 30° + S both with and without outlier detection for f = 0, 0.05, 0.05.
The WinBUGS code for the multivariate models is provided in the appendices 1 and 2 of the Additional file 1. Convergence was assessed by examination of the trace and autocorrelation plots and the Rubin-Gelman statistic after running 400 000 simulations and discarding the first 200 000 samples as 'burn in samples'.
The essential statistic should be runs scored, because runs win games.
Run your test statistic or statistics on the data you have collected.
Bill James, who popularized sabermetrics with his Baseball Abstracts in the 1980's, has developed 24 different formulas for a statistic he calls Runs Created, which factors in stolen bases, strikeouts and grounding into double plays.
