Hello SAS users !
I got panel dataset described as below
group represents fund family : In my original dataset, there are more than 300 groups for each quarter.
port represents portfolios that are hold by distinct funds within the group.
for family 1 fund 100 holds portfolio 1 and this portfolio1 holds stock 1,2,3,4,6,11 12 13 15 17 18 21 23 24
for family 1 fund 200 holds portfolio 2 and this portfolio1 holds stock ........
for family 2 fund 1001 holds portfolio 1 and so on...
portfolio 1 of family 1 and portfolio 1 of family 2 are different portfolios but it does not matter for coding.

I want to get converted dataset EFFICIENTLY!
because the original dataset is so large!

how can I do this?

Perhaps use the macro here

A datastep with an array might be the simplest:
data want; set have; array port{4} 8.; retain port:; by family; if first.family then call missing (of port{*}); if ... then ...; if last.family then output; run;
I am afraid this is incomplete because I have no idea what the 1's and 0's mean, or what the logic here is. For instance, in row 1 of the required output, port3=1, I cannot see any reason for this?
I am afraid that does not make sense to me, I do not work in your industry or with your data. The first row of your required output shows:
family | stock | port1 | port2 | port3 | port4 |
1 | 1 | 1 | 0 | 1 | . |
And the first row of the test data - the only one relating to the above as far as I can see:
input family port fund stock;
datalines;
1 1 100 1
There is nothing there which would indicate that port 2 should be 0, port3 should be 1, nor that port4 should be missing?
with all do respect don't you have a dataset 'have'
row=72? (provided code)
in row=29
there are
family port fund stock
1 3 300 1
right? This means that
family=1
port=3
stock=1
so that I want to have
family stock port1 port2 port3
1 1 1 0 1
zero is because for family=1 & port=2, they have no stock1
(there is no such row in dataset 'have' with value
family=1 & port=2 & stock=1)
Ah I see, not sorted. This works:
proc sort data=have; by family stock; run; data want (drop=port fund); set have; array p{4} 8; retain p:; by family stock; if first.stock then call missing(of p{*}); p{port}=1; if last.stock then output; run;
I think for that you would need an additional few lines:
proc sort data=have; by family stock; run; data want (drop=port fund i on); set have; array p{4} 8; retain p:; by family stock; if first.stock then call missing(of p{*}); p{port}=1; if last.stock then do;
on=0;
do i=4 to 1 by -1;
if p{i}=1 then on=1;
if on=1 and p{i}=. then p{i}=0;
end;
output;
end; run;
I haven't tested, but something like that should work, so basically loop back across the array from end to start, when hit the first 1 set a variable to on, then any of the array before that if missing becomes 0 rather than .
