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 6/30/2016 \$763,615 8/15/2016 \$17,868,981

Re: Anyone know how to use the IRR function?

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;

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;

Oleg,

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