This dialog lets you specify output and options for meta analysis.

## Display

Specifies which items of output are to be displayed in the Output window.

Estimates |
The estimates from the individual trials and the combined estimates, with standard errors and confidence intervals |

Overall test |
Overall tests using the combined estimates |

Heterogeneity |
Test for heterogeneity of the estimates across trials |

Monitoring |
Monitoring information from the estimation when using maximum likelihood, maximum REML likelihood or REML. |

## Graphics

Specifies the plots to be displayed.

Confidence plot |
Plot of the individual and combined estimates, and their confidence intervals |

Galbraith plot |
Plot of the standardized estimates against their precision i.e. the reciprocal of the standard error (also known as a radial plot) |

## Confidence limit (%)

Lets you control the confidence limit to use for the confidence intervals. The limit is expressed as a percentage and must be in the range 0-100.

## Method for calculating random estimate confidence interval

Specifies how to calculate the confidence interval for a random estimate formed by either maximum likelihood or REML. You can select either **Profile likelihood** or **Normal approximation**.

## Type of test for overall probability values

Controls the type of test to use for the overall probability values. You can select either **Greater than**, **Less than** or T**wo-sided**.

## Method to form combined estimates

The method to use to form the combined estimates formed assuming that the estimates are random.

Maximum likelihood |
Estimates the variance component of the random effects using maximum likelihood |

Maximum REML likelihood |
Estimates the variance component of the random effects by maximizing the REML likelihood |

Moments |
Estimates the variance component of the random effects using the method of moments |

REML |
Estimates the variance component of the random effects using REML |

The maximum REML likelihood setting is based on the same criterion as the REML setting, but it programs the maximization explicitly, in a FOR loop. It thus provides an alternative to use if the REML experiences convergence problems.

## Maximum number of iterations

This specifies the maximum number of iterations to use with maximum likelihood and maximum REML likelihood (default 100).

## Tolerance

Specifies the convergence criterion (default 10^{-6}).
