    Confidence Interval Distribution

    +

    When determining confidence intervals around means using standard distributions (rather than a + boostrap procedure), the traditional approach in meta-analysis has generally been to use a Normal + distribution. In earlier versions of MetaWin, we used Student's t + distribution instead, because we thought it useful to account for the uncertainty in estimation due + to the small number of studies often found in meta-analyses. With this new version, the user can + specify which distribution they wish to use, with the Normal distribution set as default. +

    +

    To change the distribution, choose the item under the + Options→Analysis Options menu, which will toggle between the two + distributions. The current distribution is indicated by the icon to the left of the menu option + (either a Z or a t), as well as by the text + of the menu item which specifies the distributions being changed both "from" and "to". + MetaWin will attempt to remember this choice the next time you run the + program.

    +

    The specified distribution is also listed as one of the user-specified parameters at the beginning of + analysis output.
