Result from boosting a temporal response function

  • h (NDVar | tuple of NDVar) – The temporal response function. Whether h is an NDVar or a tuple of NDVars depends on whether the x parameter to boosting() was an NDVar or a sequence of NDVars.

  • h_scaled (NDVar | tuple of NDVar) – h scaled such that it applies to the original input y and x. If boosting was done with scale_data=False, h_scaled is the same as h.

  • h_source (NDVar | tuple of NDVar) – If h was constructed using a basis, h_source represents the source of h before being convolved with the basis.

  • h_time (UTS) – Time dimension of the kernel.

  • r (float | NDVar) – Correlation between the measured response and the response predicted with h. Type depends on the y parameter to boosting(). For vector data, measured and predicted responses are normalized, and r is computed as the average dot product over time.

  • r_rank (float | NDVar) – As r, the Spearman rank correlation.

  • t_run (float) – Time it took to run the boosting algorithm (in seconds).

  • error (str) – The error evaluation method used.

  • residual (float | NDVar) –

    The residual of the final result

    • error='l1': the sum of the absolute differences between y and h * x.

    • error='l2': the sum of the squared differences between y and h * x.

    For vector y, the error is defined based on the distance in space for each data point.

  • delta (scalar) – Kernel modification step used.

  • mindelta (None | scalar) – Mindelta parameter used.

  • n_samples (int) – Number of samples in the input data time axis.

  • scale_data (bool) – Scale_data parameter used.

  • y_mean (NDVar | scalar) – Mean that was subtracted from y.

  • y_scale (NDVar | scalar) – Scale by which y was divided.

  • x_mean (NDVar | scalar | tuple) – Mean that was subtracted from x.

  • x_scale (NDVar | scalar | tuple) – Scale by which x was divided.

  • splits (Splits) – Data splits used for cross-validation. Use splits.plot() to visualize the cross-validation scheme.

  • algorithm_version (int) – Version of the algorithm with which the model was estimated; -1 for results from before this attribute was added.
