.Fishers
- 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
Masking approaches which average across voxels (e.g., NiftiLabelsMaskers) will result in invalid results. It cannot be used with these types of maskers.
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, drop_invalid=True)[source]
Fit Estimator to Dataset.
- Parameters
dataset (
nimare.dataset.Dataset
) – Dataset object to analyze.drop_invalid (
bool
, optional) – Whether to automatically ignore any studies without the required data or not. Default is False.
- Returns
nimare.results.MetaResult
– Results of Estimator fitting.- Variables
inputs_ (
dict
) – Inputs used in _fit.
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
.
