cajools

OLS regression of VECM

Description

This function returns the OLS regressions of an unrestricted VECM, i.e. it returns an object of class lm. The user can provide a certain number of which equation in the VECM should be estimated and reported, or if "reg.number=NULL" each equation in the VECM will be estimated and its results are reported.

Usage

cajools(z, reg.number = NULL)

Arguments

`z`	An object of class `ca.jo` or `cajo.test`.
`reg.number`	The number of the equation in the VECM that should be estimated or if set to `NULL` (the default), all equations within the VECM are estimated.

Value

Returns an object of class lm.
