Hi all,

I have the data set provided below:-

Data have;

input start end score;

Datalines;

1 0 0.22

1 1 0.58

2 2 0.89

6 3 0.36

3 2 0.77

1 0 0.89

1 1 0.89

;

run;

“start” variable shows number of observations at start of period, while “end” shows the number of default observations at the end of period. With given data/scenario I have to create default indicator with 1 as default and 0 as not default. For example observation number 4 has value 6 for start variable and it has 3 defaults within the end variable so I need to replicate that observation 6 times i.e. 3 times with value 1 in the default indicator(“def_indi”) and 3 times with value 0.

Through my code I find myself successful in replicating the observation but not in creating the default indicator as desired. The desired data “want” is provided below.

My partial code:-

data want;

set have;

do i= 1 to (start);

def_indi=1;

output;

end;

run;

Data want;

input start end score Def_indi;

Datalines;

1 0 0.22 0

1 1 0.58 1

2 2 0.89 1

2 2 0.89 1

6 3 0.36 0

6 3 0.36 0

6 3 0.36 0

6 3 0.36 1

6 3 0.36 1

6 3 0.36 1

3 2 0.77 0

3 2 0.77 1

3 2 0.77 1

1 0 0.89 0

1 1 0.89 1

;

run;

I need it urgently so I would be highly thankful if someone could help me with it.

Tony
