I have data with all 4 quarter data however when i do Proc Expand and convert from Qtr to Month its only giving up to October data . 

New_date is formated as YYq.

 

proc expand data=MS_score1 out=MS_score from=qtr to=month;
convert MDHCP;
by RID FullName;
id new_date;
run;

 

how to get the other two months

The problem  is in the CONVERT statement, namely the "/observed=..." parameter.  When absent, this parameter defaults to "beginning", as in

     convert mdhcp /observed=(beginning,beginning);

 

which tells expand that both the incoming data and the outgoing data represent the "beginning" of the interval.  So for from=qtr to=month it means that the last outgoing item is for the beginning of the interval, namely october for quarter 4.

 

try something like

   convert mdhcp/observed=(total,total);

 

which should divide up each  MDHCP into 3 almost-equal amounts. I say  "almost equal" because the number of days in various months are "almost  equal".

 

Another option

 convert mdhcp/observed=(average,average);

 

which would work if mchcp is a  daily rate, recorded over a month, and you want daily rates for months.

For a problem like this we also need sample data to replicate your issue.
