Analysis data filtering.
- nifreeze.analysis.filtering.normalize(x: ndarray)[source]¶
Normalize data using the z-score.
The z-score normalization is computed as:
\[z_i = \frac{x_i - \mu}{\sigma}\]where \(x_i\) is the framewise displacement at point \(i\), \(\mu\) is the mean of all values, \(\sigma\) is the standard deviation of the values, and \(z_i\) is the normalized z-score.
