Generic function for performing structural change tests.

`sctest(x, …)`

x

an object.

…

arguments passed to methods.

An object of class `"htest"`

containing:

the test statistic,

the corresponding p value,

a character string with the method used,

a character string with the data name.

`sctest`

is a generic function for performing/extracting structural
change tests based on various types of objects. The `strucchange`

package
provides various types of methods.

First, structural change tests based on
F statistics in linear regression models (`Fstats`

),
empirical fluctuation processes in linear regression models (`efp`

),
and generalized empirical fluctuation processes in parametric models (`gefp`

)
are available in the corresponding `sctest`

methods.

Second, convenience interfaces for carrying out structural change tests
in linear regression models and general parametric models are provided in
`sctest.formula`

and `sctest.default`

, respectively.
