Generates random odds ratios, logged odds ratios, and their variances (Cornfield 1951).

K |
Number of effect sizes to generate. |
p_A |
The odds of the event of interest for Group A. A probability ranging from zero to one. |
N_A |
The total number of samples of Group A. |
p_B |
The odds of the event of interest for Group B. A probability ranging from zero to one. |
N_B |
The total number of samples of Group B. |
continuity |
Odds ratios with zero events cannot be computed. Following, Cox (1970), a continuity correction can be added to each cell of the 2 by 2 table to help improve this problem of zero events within the table. The default value added is 0.5. |
logged |
When |
A data table with columns of random effect sizes (OR) and their variances.
