# timeatlas.processors.Scaler.zscore¶

static Scaler.zscore(ts: TimeSeries) → TimeSeries

Scale a TimeSeries values by removing the mean and scaling to unit variance

$z = \frac{x - \mu}{\sigma}$
where :
• $$z$$ is the scaled value

• $$x$$ is the value

• $$\mu$$ is the mean of the time series

• $$\sigma$$ is the standard deviation of the time series

Parameters

ts – TimeSeries to scale

Returns

TimeSeries
