Perform a sensitivity analysis

As part of a sensitivity analysis we might want to assess the impact of each study on the combined effect.  For example, what was the impact on the combined effect of an outlier or of an especially large study?  Or, did a small study have any impact at all?

To address these kinds of questions the program will automatically run the analysis with all studies except the first, then all studies except the second, and so on.  The resulting plot shows the impact of each study at a glance.

Additionally, you have the option of running the analysis with any study or set of studies removed – these can be selected by name, or by the value of a moderator variable.
