-
As I pointed out here, this statistic is readily "studentized" (or normalized) by defining the studentized G (n,N) = the proportion of cases in a 50-50 binomial draw of length N which are less informative than n out of N.
-
Top – Gleichlàƒ⣵figkeit G; bottom – "studentized" G.
-
For example, if there is a 50-50 split between + and – in a given year, the studentized G would be 0 since you get at least that good a match 100% of the time.
-
On the other hand, if you have 23 of 23 cores going the same way, the studentized G is nearly 1.
-
If you get 2 out of 2 going the same way, the studentized G is only 0.5, since you get a less "informative" result 1 up, 1 down 50% of the time.
-
The studentized G provided a much better estimate of signal reliability.
-
I tried the following definition for a "studentized G" statistic:
-
If you get 2 out of 2 going the same way, the studentized G is 0.5, since you get a less "informative" result 1 up, 1 down 50% of the time.
-
Opposite stories are given by the Esper G and the studentized G: the Esper G indicates very high signal reliability in the early portion, while a studentized G shows extremely poor signal reliability in the early portion.
-
For example, if there is a 50-50 split between + and -, the studentized G would be 0 since you get at least that good a match 100% of the time.
