(y, x, tstart, tstop, scale_data, delta, mindelta, error, basis, basis_window, partitions_arg, partitions, model, prefit, h, r, isnan, spearmanr, residual, t_run, y_mean, y_scale, x_mean, x_scale, y_info={}, r_l1=None, selective_stopping=0, n_samples=None, **debug_attrs)¶ Result from boosting a temporal response function
Attributes:  h : NDVar  tuple of NDVar
The temporal response function. Whether
h
is an NDVar or a tuple of NDVars depends on whether thex
parameter toboosting()
was an NDVar or a sequence of NDVars. h_scaled : NDVar  tuple of NDVar
h
scaled such that it applies to the original inputy
andx
. If boosting was done withscale_data=False
,h_scaled
is the same ash
. h_source : NDVar  tuple of NDVar
If
h
was constructed using a basis,h_source
represents the source ofh
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 they
parameter toboosting()
. spearmanr : 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 betweeny
andh * x
.error='l2'
: the sum of the squared differences betweeny
andh * 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. partitions : int
Numbers of partitions of the data used for cross validation.
