lagbounds

lag bounds in a regression

CALLING SEQUENCE

[bounds_out]=lagbounds(bounds_in,l)

PARAMETERS

Input

* bounds_in = the original bounds

* l = the lag (positive or negative, if you want to extend bounds in the past)

 

Output

* bounds_out = the lagged bounds

DESCRIPTION

Cuts the bounds at the start of the period. If the lag is negative, then bounds are extended in the past for a number of peridos equal to the absolute value of the lag.

EXAMPLE

lagbounds(['1985q2';'1997q4'],3)
// Provides the (2x1) vector:
// ['1986q1'
// '1997q4']
 
grocer_boundsvar=lagbounds(grocer_boundsvarb,-grocer_l-1)
// taken from function cadf
