LinearModel = class LinearModel(Model) |

LinearModel(nparams, ndim=1, copy=None, **kwargs)
Anchestor of all linear models.
LinearModel implements the baseResult method needed in all linear models.
For Linear models it holds that
f( x:p ) = ∑( p_i * df( x )/dp_i )
which means that only the partial derivatives to p_i need to be given
as basePartial. The baseResult follows directly from that one.
It is implemented here.

- Method resolution order:
- LinearModel
- Model
- FixedModel
- BaseModel
- builtins.object
Constructor:
- LinearModel( nparams, ndim=1, copy=None, **kwargs )
- class for all linear models.
Parameters
----------
nparams : int
the number of parameters in this model
ndim : int
the dimensionality of the inputs (default: 1)
copy : LinearModel
model to be copied (default: None)
kwargs : dict
Possibly includes keywords from
Model : params
FixedModel : fixed, names
BaseModel : posIndex, nonZero
Methods defined here:
- baseResult( xdata, params )
- Returns the base result of linear models.
for linear models the result is the inner product of parameters
and partial derivatives.
Parameters
----------
xdata : array_like
values at which to calculate the result
params : array_like
values for the parameters.
