class
Fishers
(*args, **kwargs)[source]¶ Bases:
nimare.base.MetaEstimator
An image-based meta-analytic test using t- or z-statistic images. Requires z-statistic images, but will be extended to work with t-statistic images as well.
Notes
Requires
z
images.Warning
This method does not currently calculate p-values correctly. Do not use.
All image-based meta-analysis estimators adopt an aggressive masking strategy, in which any voxels with a value of zero in any of the input maps will be removed from the analysis.

fit
(dataset)[source]¶ Fit Estimator to Dataset.
- Parameters
dataset (
nimare.dataset.Dataset
) – Dataset object to analyze.- Returns
nimare.results.MetaResult
– Results of Estimator fitting.
Notes
The
fit
method is a light wrapper that runs input validation and preprocessing before fitting the actual model. Estimators’ individual “fitting” methods are implemented as_fit
, although users should callfit
.
