Counting Periods

jjadall1 — Mon, 12 Mar 2018 20:46:55 GMT

Hello SAS Support Communities,

I have a few variables left to calculate for this portion of my dissertation. One of them is calculating the number of quarters covered between rpb and rpe. The periods1 dataset is the starting point. The fyr variable is the month of the end of a fiscal year. For instance, observation 1 has an fyr of 12. That means 12/31 is the end of the fiscal year.

In the periods1b dataset, fyr1a is the beginning of the fiscal year. In observation 1, fyr1a is 1 which means that 1/1 is the beginning of the fiscal year.

Periods2 is the way the dataset should look. Each quarter counts as 0.25. Observation 1 covers 3 years (4 quarters per year for 3 years). Therefore, the periods variable = 3;

Look at observation 2. Fyr is 7, meaning 7/31 is the end of the fiscal year. Since restatement period is from 7/1/2013 through 7/31/2014, parts of 5 quarters are covered (7/1/2013 through 7/31/2013, 8/1/2013 through 10/31/2013, 11/1/2013 through 1/31/2013, 2/1/2014 through 4/30/2014, and 5/1/2014 through 7/31/2014). Therefore, the periods variable = 1.25 (0.25 X 5).

I tried using the intck function as follows:

data dissert1.periods1c;

set dissert1.periods1b;

quarters=intck(qtr,rpb,rpe,'C');

run;

I received the following error in the log:

3052 quarters=intck('qtr','rpb''d,'rpe'd);

---

ERROR 76-322: Syntax error, statement will be ignored.

3066 data dissert1.periods1c;

3067 set dissert1.periods1b;

3068 quarters=intck(qtr,rpb,rpe,'C');

3069 run;

How should I resolve this?

Thank you so much in advance for your help!

God bless, best regards, and take care,

Try

quarters=intck('qtr',rpb,rpe);

if these 2 variables are sas dates.

Thank you Chris. I received output, which is progress. However, the fyr issue was not taken into consideration and, therefore, some of the results are wrong.

Please post a few lines of:

- existing data

- wanted data

I am not downloading zip files.

The lines don't have to be complete data, just a sample to illustrate the calculations you need.

I download Microsoft files even less.

Please post data as data steps (and check that they run fine).

Periods1a Dataset:

CIK	fyr	rpb	rpe
1234367	12	1/1/2007	12/31/2009
1576888	7	6/30/2013	7/31/2014
2008765	5	3/1/2012	6/15/2013
6875330	12	1/1/2013	1/31/2014
9877364	9	10/1/2011	9/30/2012

Fyr is the end of a fiscal year.

Periods1b Dataset:

CIK	fyr	rpb	rpe	fyr1	fyr1a
1234367	12	1/1/2007	12/31/2009	13	1
1576888	7	6/30/2013	7/31/2014	8	8
2008765	5	3/1/2012	6/15/2013	6	6
6875330	12	1/1/2013	1/31/2014	13	1
9877364	9	10/1/2011	9/30/2012	10	10

Fyr1a is the beginning of a fiscal year.

Periods2 Dataset (what I want):

CIK	fyr	rpb	rpe	Periods
1234367	12	1/1/2007	12/31/2009	3
1576888	7	7/1/2013	7/31/2014	1.25
2008765	5	3/1/2012	6/15/2013	1.5
6875330	12	1/1/2013	1/31/2014	1.25
9877364	9	10/1/2011	9/30/2012	1

With observation 1, there are 3 years that are covered.

With observation 2, 7/1/2013 is in the quarter that ends 7/31/2013. That is 0.25 and 1 year (8/1/2013 through 7/31/2014) to get 1.25.

God bless, best regards, and thanks again Chris!

I think that the following does what you want. It only uses the periods1a dataset:

data periods1a;
  infile cards dlm=',' dsd;
  input CIK fyr rpb : mmddyy10. rpe : mmddyy10.;
  format rpb rpe mmddyy10.;
  cards;
1234367,12,1/1/2007,12/31/2009
1576888,7,7/1/2013,7/31/2014
2008765,5,3/1/2012,6/15/2013
6875330,12,1/1/2013,1/31/2014
9877364,9,10/1/2011,9/30/2012
;

data want;
  set periods1a;
  Periods=(intck(catt('qtr.',mod(fyr,3)+1),rpb,rpe)+1)/4;
run;
