Better code to caulculae Tamhil_bads Tamhil_goods

Ronein — Sat, 20 Feb 2021 11:16:07 GMT

Hello

Is there a better way with less code to calculated the following for each team category:

Number of customers

Number of bad customers

Number of good customers

Percent of bad customers in each category

proprtion of bad customers from all bad customers

proprtion of good customers from all good customers

Please provide solution in the following ways:

1-Proc sql

2-proc report

3-proc tabulate

4-proc summary

Data tbl;
Input ID Team Ind_Fail;
Cards;
1 a 0
2 a 1
3 b 0
4 b 1
5 a 0
6 b 0
7 a 1
8 a 0
9 b 1
;
Run;
 
Proc sql;
Create table as wanted_a as
Select  Team,
Count(*) as nr_customers,   
Sum(Ind_Fail) as nr_bads,
Sum(calculated  nr_customers,- calculated nr_fails) as Nr_goods ,
Calculated nr_bads/ Calculated nr_customers as PCT_bads
From tbl
Group by Team
;
Quit;





Proc sql;
Create table as wanted_b as
Select  Count(*) as  Total_nr_customers,   
Sum(Ind_Fail) as Total_nr_bads,
Sum(calculated  Total_nr_customers,- calculated Total_nr_fails) as Total_Nr_goods 
From tbl
Group by Team
;
Quit;

Data  wanted_c;
Merge wanted_a (in=a) wanted_b(in=b);
proportion_good=Nr_goods/Total_Nr_goods;
proportion_bads=nr_bads/ Total_Nr_bads;
Format proportion_good proportion_bads comma8.2;
Run;

Compare your first sql to next fixed code:

Data tbl;
Input ID Team $ Ind_Fail;
Cards;
1 a 0
2 a 1
3 b 0
4 b 1
5 a 0
6 b 0
7 a 1
8 a 0
9 b 1
;
Run;
 
Proc sql;
	Create table wanted_a as
	Select  Team,
	Count(*) as nr_customers,   
	Sum(Ind_Fail) as nr_bads,
	Sum(calculated  nr_customers,- calculated nr_bads) as Nr_goods ,
	Calculated nr_bads/ Calculated nr_customers as PCT_bads
	From tbl
	Group by Team
;
Quit;

Thank you, however in this code there is no calculation of :proportion_good ,proportion_bads.

I have added the required:

Proc sql;
	Create table wanted_a as
	Select  Team,
	Count(*) as nr_customers,   
	Sum(Ind_Fail) as nr_bads,
	Sum(calculated  nr_customers,- calculated nr_bads) as Nr_goods ,
	Calculated nr_bads/ Calculated nr_customers as PCT_bads format percent5.2
	From tbl
	Group by Team
   ;
   create table wanted_b as 
   select sum(nr_bads) / sum(nr_customers) as proportion_bads format 4.3,
          1- calculated proportion_bads as proportion_good  format 4.3
   from wanted_a
  ;
   create table want_c as 
   select a.*, b.*
   from wanted_a as a , wanted_b as b 
  ;
Quit;

sum(nr_bads) / sum(nr_customers) as proportion_bads
is not correct because need to calculate number of bads in each category divided by total number of bads....
Maybe this solution will work well? But still using here 3 proc sql so didnt save code....

Proc sql;
Create table wanted_a as
Select Team,
Count(*) as nr_customers,
Sum(Ind_Fail) as nr_bads,
Sum(calculated nr_customers,- calculated nr_bads) as Nr_goods ,
Calculated nr_bads/ Calculated nr_customers as PCT_bads format percent5.2
From tbl
Group by Team
;
create table wanted_b as
select nr_bads/ sum(nr_bads) as proportion_bads format 4.3,
Nr_goods /sum(Nr_goods ) as proportion_goods format 4.3
from wanted_a
;
create table want_c as
select a.*, b.*
from wanted_a as a , wanted_b as b
;
Quit;

May anyone show ways to do it with proc report/proc tabulate?
