span.TSestModel: Calculate Span of Tangent Plane

In curve: Dynamic Systems Estimation - Curvature Extensions

Description

Calculate the dimension of the tangent space

Usage

    ## S3 method for class 'TSestModel'
span(func, x=coef(func),
        method="Richardson", method.args=list(d=0.01, eps=1e-4, r=6, v=2),
     show.details=FALSE, compiled=.DSEflags()$COMPILED,
     Shape=TSmodel(func), data=TSdata(func), ...)

Arguments

func	a TSestModel object which is used as a function mapping coefficients (parameters) to residuals.
x	parameter vector first argument to function func indicating the point with respect to which the derivative is calculated.
show.details	logical indicating if detailed calculations should be shown.
compiled	use the compiled version of the code. (FALSE only for debugging.)
method	string indicating the numerical approximation method.
method.args	list with arguments to method (see grad).
Shape	a TSmodel in which the parameters should be used.
data	TSdata to use in teh evaluation.
...	additional arguments passed to func.

Details

See the generic function.

Value

The singular values of the matrix of tangent vectors are returned.

Side Effects

If show.details is TRUE then intermediate calculations are printed.
