The statistic was described in Killeen (2005).

Here is the simple version...

1. Conduct your statistical test and obtain a p value.

2. Calculate the z score for 1-p.

3. Divide that value by the square root of 2.

4. Find the p value that corresponds to the new z score.

In other words,

p rep = NormalCumDistribution (InverseNormalCumDistribution(1-p)/SqrRoot(2))

Hi folks . . . Does anyone out there have any guidance as to how to go about calculating 
"p rep" (the probability of replication), which is the new statistic of choice 
for submissions to Psychological Science?

Cheers,
