Hi,
Does anyone know if Stata automatically uses Freeman-Holton's Extension to Fisher's Exact test when handing contingency tables larger than 2X2? The Stata Help Menu indicates the following (see below), so it appears that Stata does use some methods to handle rxc tables. A reviewer asked if this extension was applied in our analysis in Stata. I searched online but was not sure if Stata used this method automatically when doing Fisher's Exact with rxc tables.Would appreciate your opinion. Thanks very much.
Sincerely
MN
“exact[(#)] displays the significance calculated by Fisher's exact test and may be applied to r x c as well as to 2 x 2 tables. For 2 x 2 tables, both one- and two-sided probabilities are displayed. For r x c tables, two-sided probabilities are displayed. The optional positive integer # is a multiplier on the amount of memory that the command is permitted to consume. The default is 1. This option should not be necessary for reasonable r x c tables. If the command terminates with error 910, try exact(2). The maximum row or column dimension allowed when computing Fisher's exact test is the maximum row or column dimension for tabulate (see limits).”
