mne.simulation.metrics.precision_score

mne.simulation.metrics.precision_score(stc_true, stc_est, threshold='90%', per_sample=True)

Compute the precision.

The precision is the ratio tp / (tp + fp) where tp is the number of true positives and fp the number of false positives. The precision is intuitively the ability of the classifier not to label as positive a sample that is negative.

The best value is 1 and the worst value is 0.

Threshold is used first for data binarization.

Parameters:

stc_trueinstance of (Vol|Mixed)SourceEstimate

The source estimates containing correct values.

stc_estinstance of (Vol|Mixed)SourceEstimate

The source estimates containing estimated values e.g. obtained with a source imaging method.

thresholdfloat | str

The threshold to apply to source estimates before computing the precision. If a string the threshold is a percentage and it should end with the percent character.

per_samplebool

If True the metric is computed for each sample separately. If False, the metric is spatio-temporal.

Returns:

metricfloat | array, shape (n_times,)

The metric. float if per_sample is False, else array with the values computed for each time point.
