Linear Regression Traces¶

The linear regression trace collection is used to store the resulting signal traces produced by the moving linear regression over the samples of a signal trace.

Create the Trace Collection¶

You can create a linear regression trace collection without samples by calling the LinearRegressionTraces class.

>>> # create an empty linear regression trace collection
>>> traces = LinearRegressionTraces()
>>> traces
LinearRegressionTraces(level=Trace(label='Trace', samples=[]),
                       slope=Trace(label='Trace', samples=[]),
                       intercept=Trace(label='Trace', samples=[]),
                       mean=Trace(label='Trace', samples=[]),
                       median=Trace(label='Trace', samples=[]),
                       minimum=Trace(label='Trace', samples=[]),
                       maximum=Trace(label='Trace', samples=[]),
                       range=Trace(label='Trace', samples=[]),
                       error=Trace(label='Trace', samples=[]),
                       negative_error=Trace(label='Trace', samples=[]),
                       positive_error=Trace(label='Trace', samples=[]),
                       absolute_error=Trace(label='Trace', samples=[]),
                       variance=Trace(label='Trace', samples=[]),
                       deviation=Trace(label='Trace', samples=[]),
                       skew=Trace(label='Trace', samples=[]),
                       kurtosis=Trace(label='Trace', samples=[]))
