SALAM HI
Everyone
I HAVE DATA ON 65 VARIABLES FROM 1980 TO 2000 FOR 94 INDIVIDUALS
THE ISSUE IS THAT , I HAVE TO FILLING THE MISSING VALUES.
1) IF THE IN BETWEEN VALUES ARE MISSING THEN, HAVE TO USE THE FOLLOWING FORMULA.
AS IN THE ABOVE CASE TWO VALUES ARE MISSING, SO ONE HAS TO USE 3 IN THE FORMULA. IF 3 VALUES ARE MISSING THEN 4 AND SO ON.
2) BUT IF THE VALUES ARE MISSING AT THE START OR END THEN FIRST OF ALL ONE HAS TO FINE THE GROWTH RATE OF THE LAST 5 KNOW VALUES AND AFTER FIND THE GROWTH , ONE WILLL FORECAST THE NEXT VALUES.
LIKE
NOTE : IF MORE THAN FIVE VALUES ARE MISSING FOR ANY INDIVIDUAL DO NOT FILL IN THOSE.
3)
IF THE STARTING FIVE VALUES ARE MISSING I HAVE TO DO THE SAME AS THE VALUES ARE MISSING AT THE LAST.
FIND THE GROWTH RATE OF LAST FIVE KNOW VALUES AND THEN FORECAST THE PREVIOUS VALUES.
LIKE
ANY HELP ON THIS
THANKS
