Matching columns with rows

Agent1592 — Sun, 15 Jan 2017 19:23:29 GMT

Have table:

CompanyID	YEAR	DE	DA	WC	Type	Ratio_Type
1	1996	0.448745476	0.22336778	1.474	Max. DE	2
1	1996	0.448745476	0.22336778	1.474	Max. DA	0.5
1	1996	0.448745476	0.22336778	1.474	Min. WC	1.5
1	1996	0.448745476	0.22336778	1.474	Max. DE	2
1	1996	0.448745476	0.22336778	1.474	Max. DA	0.5
1	1996	0.448745476	0.22336778	1.474	Min. WC	1.5
1	1997	0.648033979	0.26507138	1.474	Max. DE	2
1	1997	0.648033979	0.26507138	1.474	Max. DA	0.5
1	1997	0.648033979	0.26507138	1.474	Min. WC	1.5
2	1997	0.648033979	0.26507138	1.474	Max. DE	2
2	1997	0.648033979	0.26507138	1.474	Max. DA	0.5
2	1997	0.648033979	0.26507138	1.474	Min. WC	1.5
2	1997	0.648033979	0.26507138	1.474	Max. DE	2
2	1997	0.648033979	0.26507138	1.474	Max. DA	0.5
2	1997	0.648033979	0.26507138	1.474	Min. WC	1.5
2	1997	0.648033979	0.26507138	1.474	Max. DA	0.6
2	1997	0.648033979	0.26507138	1.474	Min. WC	1.5

I would like to match the type column with the previous 3 columns and calculate the difference betwee the actual ratio and the maximum or minimum ratio.

The want table is the following:

CompanyID	YEAR	DE	DA	WC	Type	Ratio_Type	Difference
1	1996	0.448745476	0.22336778	1.474	Max. DE	2	1.551255
1	1996	0.448745476	0.22336778	1.474	Max. DA	0.5	0.276632
1	1996	0.448745476	0.22336778	1.474	Min. WC	1.5	-0.026
1	1996	0.448745476	0.22336778	1.474	Max. DE	2	1.551255
1	1996	0.448745476	0.22336778	1.474	Max. DA	0.5	0.276632
1	1996	0.448745476	0.22336778	1.474	Min. WC	1.5	-0.026
1	1997	0.648033979	0.26507138	1.474	Max. DE	2	1.351966
1	1997	0.648033979	0.26507138	1.474	Max. DA	0.5	0.234929
1	1997	0.648033979	0.26507138	1.474	Min. WC	1.5	-0.026
2	1997	0.648033979	0.26507138	1.474	Max. DE	2	1.351966
2	1997	0.648033979	0.26507138	1.474	Max. DA	0.5	0.234929
2	1997	0.648033979	0.26507138	1.474	Min. WC	1.5	-0.026
2	1997	0.648033979	0.26507138	1.474	Max. DE	2	1.351966
2	1997	0.648033979	0.26507138	1.474	Max. DA	0.5	0.234929
2	1997	0.648033979	0.26507138	1.474	Min. WC	1.5	-0.026
2	1997	0.648033979	0.26507138	1.474	Max. DA	0.6	0.334929
2	1997	0.648033979	0.26507138	1.474	Min. WC	1.5	-0.026

Please note that the difference is calculated differently for the Min. and Max. ratios.

If I can get the SAS SQL code for this I would really appreciate it.

Re: Matching columns with rows

art297 — Sun, 15 Jan 2017 19:34:38 GMT

Using your example data, please show how the difference is calculated (for at least one of the min and max examples)

Re: Matching columns with rows

Agent1592 — Sun, 15 Jan 2017 19:43:38 GMT

Sorry I attached an Excel file. Difference in cell H2=G2-C2.

Difference= the value from the row of "Ratio_Type" minus the value from the DE column if the value in Type column is equal to "Max. DE".

Sorry, didn't see the workbook. The following should do what you want:

proc sql;
create table want as
select *,
case
when scan(type,1,' ') eq 'Max.' and scan(type,2,' ') eq 'DE' then ratio_type-DE
when scan(type,1,' ') eq 'Min.' and scan(type,2,' ') eq 'DE' then DE-ratio_type
when scan(type,1,' ') eq 'Max.' and scan(type,2,' ') eq 'DA' then ratio_type-DA
when scan(type,1,' ') eq 'Min.' and scan(type,2,' ') eq 'DA' then DA-ratio_type
when scan(type,1,' ') eq 'Max.' and scan(type,2,' ') eq 'WC' then ratio_type-WC
when scan(type,1,' ') eq 'Min.' and scan(type,2,' ') eq 'WC' then WC-ratio_type
end as difference
from have
;
quit;

Thanks Art:

I simplified the table and consolidated the rows.

I have the following table:

CompanyID	YEAR	DE	DA	WC	Max. DE	Max. DA	Min. WC
1	1996	0.448745476	0.22336778	1.474	2		1
1	1997	0.448745476	0.22336778	1.474	1
2	1996	0.648033979	0.26507138	1.474	1.5	6	7
2	1997	0.648033979	0.26507138	1.474		1

I want the table:

CompanyID	YEAR	DE	DA	WC	Max. DE	Max. DA	Min. WC	Diff_DE	Diff_DA	Diff_DC
1	1996	0.448745476	0.22336778	1.474	2		1	1.551255		0.474
1	1997	0.448745476	0.22336778	1.474	1			0.551255
2	1996	0.648033979	0.26507138	1.474	1.5	6	7	0.851966	5.734929	-5.526
2	1997	0.648033979	0.26507138	1.474		1			0.734929

Is this code going to be the same? I also have the attachment.

Re: Matching columns with rows

art297 — Sun, 15 Jan 2017 23:25:29 GMT

No, but the following code would:

proc sql;
create table want as
select *,
Max_DE-DE as Diff_DE,
Max_DA-DA as Diff_DA,
WC-Min_WC as Diff_DC
from have
;
quit;
