Anyone know how to use the IRR function?

I have a variable with 10 quarters of cash flow. It looks like the following: The variable in SAS is called Axiom. I want to calculate the IRR but I am not sure how. I looked it up but still confused. Thank you,

Date	Axiom
6/30/2013	($17,601,671)
9/30/2013	$575,049
12/31/2013	$575,049
3/31/2014	$562,548
6/30/2014	$568,799
9/30/2014	$819,636
12/31/2014	$812,448
3/31/2015	$793,071
6/30/2015	$792,055
9/30/2015	$790,883
12/31/2015	$783,695
3/31/2016	$770,725

Hi.

Try the code below.

data have;

infile cards;

informat Date mmddyy10. Axiom dollar10.;

input date axiom;

format date ddmmyy10.;

cards;

6/30/2013 ($17,601,671)

9/30/2013 $575,049

12/31/2013 $575,049

3/31/2014 $562,548

6/30/2014 $568,799

9/30/2014 $819,636

12/31/2014 $812,448

3/31/2015 $793,071

6/30/2015 $792,055

9/30/2015 $790,883

12/31/2015 $783,695

3/31/2016 $770,725

6/30/2016 $763,615

8/15/2016 $17,868,981

;

proc transpose data=have out=have1; var axiom; run;

data want; set have1;

irr=irr(4,of col:);

run;

Note:

I make some experiments calculating IRR in Excel and SAS.

The calculation in Excel and SAS equals if make a daily cash flow both in Excel and SAS. I mean you have 6/30/2013 7/1/2013 7/2/2013 ... and so on 365 points per year most of them are missing or equals zero.

Then you can use IRR=IRR(365, of col:);

Oleg,

It worked perfectly. Thank you for the second email since making a daily data set was the key.
