Function to create a regressionplot()

Good morning everybody,

I'm struggling at realizing a portion of code which allows me to automatically extrapolate the set of data to compose the object for the regressionplot() function, which requires a Tx2 matrix.

So let's make an example of my matrix with elements which indicate only the date of the "regression" event (montlhy data):

[31/05/2000

02/06/2001

03/06/2001

05/06/2002

06/06/2002

07/06/2002 ]

and the result which I want to obtain to use in the recessionplot() should be:

[31/05/2000 01/06/2000

02/06/2001 04/06/2001

05/06/2001 08/06/2001]

In order ot allow the presence of recession shadow also for just one month data, I need to set the closing month as i+1 (thus it is 01/06 instead of only 31/05)

How could I obtain such a Tx2 matrix?

Thank you in advance!

I hope for the dates you have respective values. Convert the dates into datenum. USe interp1 with the available data and with new date.

Yes, each time my X value is lower than the median computed, I have a recession event. The problem is that I have to select just the starting date and ending date (ending+1) for the regression plot
