I want to do some sum calculate for a data set. The challenge is I need to do both row sum AND column Sum by ID. Below is the example.
data have;
input ID var1 var2;
datalines;
1 1 1
1 3 2
1 2 3
2 0 5
2 1 3
3 0 1
;
run;
data want;
input ID var1 var2 sum;
datalines;
1 1 1 12
1 3 2 12
1 2 3 12
2 0 5 9
2 1 3 9
3 0 1 1
;
run;
Using SQL is cool, but SAS has nice data step!
proc sort data=have; by id; run;
data result;
set have;
by id;
retain sum 0;
if first.id then sum=0;
sum=sum+sum(var1,var2);
if last.id then output;
run;
proc sort data=result; by id; run;
data want;
merge have result;
by id;
run;
You will decide what to use...
Use SQL to do all of it in one step. Group only by ID, but keep var1 and var2 in the column selection. This will create the same data in want.
proc sql noprint;
create table want as
select ID
, var1
, var2
, sum(var1) + sum(var2) as sum
from have
group by ID
;
quit;

I have a data set where ID's have 2 different occurences on the same day. There are about 10 different occurences. I want to cross tabulate the occurences using proc freq or proc tabulate & find how many times each instance occurs on the same day. I want my table to look something like this
Frequency occ1 occ2 occ3 occ4 occ5 occ6
occ1 2 0 0 1 4 0
occ2 1 0 0 0 0 0
occ3 3 0 0 0 0 0
occ4 0 5 3 0 3 0
occ5 0 2 4 0 5 0
occ6 1 5 4 2 1 2
My data looks something like this
data have;
input id occurrence ;
datalines;
id1 occ3
id1 occ2
id2 occ1
id2 occ6
id3 occ2
id3 occ4
etc...
i tried
proc freq data=have;
tables occurrence*occurence ;
run;
but not having any luck.
I have tried other variations & using by ID but it gives every single ID individually & i have about 200 ID numbers.
Thanks!
Reform data so a tabulation of ordered pairs can be done.
data have;
call streaminit(2022);
do id = 1 to 20;
topic = rand('integer', 10); output;
topic = rand('integer', 10); output;
end;
run;
data stage;
do until (last.id);
set have;
by id;
row = col;
col = topic;
end;
run;
ods html file='pairfreq.html';
title "Ordered pair counts";
proc tabulate data=stage;
class row col;
table row='1st topic in id pair',col='2nd topic in id pair'*n='';
run;
ods html close;
I have a situation where I would like to put the value of a variable in the label in SAS.
Example: Median for Total_Days is 2. I would like to put this value in Days_Median_Split label. The median keeps on changing with varying data, so I would like to automate it.
Phy_Activity Total_Days "Days_Median_Split: Number of Days with Median 2"
No 0 0
No 0 0
Yes 2 1
Yes 3 1
Yes 5 1
Sample Dataset
Thanks so much!
* step 1 create data;
data have;
input Phy_Activity $ Total_Days Days_Median_Split;
datalines;
No 0 0
No 0 0
Yes 2 1
Yes 3 1
Yes 5 1
run;
*step 2 sort data on Total_days;
proc sort data = have;
by Total_days;
run;
*step 3 get count of obs;
proc sql noprint;
select count(*) into: cnt
from have;quit;
* step 4 calulate median;
%let median = %sysevalf(&cnt/2 + .5);
*step 5 get median obsevation;
proc sql noprint;
select Total_days into: medianValue
from have
where monotonic()=&median;quit;
*step 6 create label;
data have;
set have;
label Days_Median_split = 'Days_Median_split: Number of Days with Median '
%trim(&medianValue);

I have a dataset in SAS and I want to Convert one column into string by the Product. I have attached the image of input and output required.
I need the Colomn STRING in the outut. can anyone please help me ?
I have coded a data step to create the input data:
data have;
input products $
dates
value
;
datalines;
a 1 0
a 2 0
a 3 1
a 4 0
a 5 1
a 6 1
b 1 0
b 2 1
b 3 1
b 4 1
b 5 0
b 6 0
c 1 1
c 2 0
c 3 1
c 4 1
c 5 0
c 6 1

Does the following suggested solution give you what you want?:
data want;
length string $ 20;
do until(last.products);
set have;
by products;
string = catx(',',string,value);
end;
do until(last.products);
set have;
by products;
output;
end;
run;
Here's my quick solution.
data temp;
length cat $20.;
do until (last.prod);
set have;
by prod notsorted;
cat=catx(',',cat,value);
end;
drop value date;
run;
proc sql;
create table want as
select have.*, cat as string
from have inner join temp
on have.prod=temp.prod;
quit;
I have data like below
p_id E_id
---- ----
1 1
1 2
1 3
1 4
2 1
3 1
3 2
3 3
4 1
For each primary_id I have to create a table of the corresponding E_id.
How do I do it in SAS;
I am using:
proc freq data = abc;
where p_id = 1;
tables p_id * E_id;
run;
How do I generalize the where statement for all the primary keys??
The by statement is how you get a separate table for each ID. It requires data to be sorted by the variable.
proc freq data = abc;
by p_id;
tables p_id * E_id;
run;
Here is a solution allowing you to select p_id to generate frequency tables.
data have;
input p_id e_id;
datalines;
1 1
1 2
1 3
1 4
2 1
3 1
3 2
3 3
4 1
;
run;
proc sort data = have;
by p_id;
run;
%let pid_list = (1,2); ** only generate two tables;
data _null_;
set have;
by p_id;
if first.p_id and p_id in &pid_list then do;
call execute('
proc freq data = have(where = (p_id = '||p_id||'));
tables p_id * e_id;
run;
');
end;
run;
I checked out this previous post (LINK) for potential solution, but still not working. I want to sum across rows using the ID as the common identifier. The num variable is constant. The id and comp the two variables I want to use to creat a pct variable, which = sum of [comp = 1] / num
Have:
id Comp Num
1 1 2
2 0 3
3 1 1
2 1 3
1 1 2
2 1 3
Want:
id tot pct
1 2 100
2 3 0.666666667
3 1 100
Currently have:
proc sort data=have;
by id;
run;
data want;
retain tot 0;
set have;
by id;
if first.id then do;
tot = 0;
end;
if comp in (1) then tot + 1;
else tot + 0;
if last.id;
pct = tot / num;
keep id tot pct;
output;
run;
I use SQL for things like this. You can do it in a Data Step, but the SQL is more compact.
data have;
input id Comp Num;
datalines;
1 1 2
2 0 3
3 1 1
2 1 3
1 1 2
2 1 3
;
run;
proc sql noprint;
create table want as
select id,
sum(comp) as tot,
sum(comp)/count(id) as pct
from have
group by id;
quit;
Hi there is a much more elegant solution to your problem :)
proc sort data = have;
by id;
run;
data want;
do _n_ = 1 by 1 until (last.id);
set have ;
by id ;
tot = sum (tot, comp) ;
end ;
pct = tot / num ;
run;
I hope it is clear. I use sql too because I am new and the DOW loop is rather complicated but in your case its pretty straightforward.
