Hi
I have working on Panel data. For some of the individuals end values
are missing. I have to fill these values by first calculating the
growth of the known five values.
Like for the individual Aqueela values for the year 1996 – 2000 are
missing. I will first calculate the growth rate of values from
1991-1995. the formula for calculating the growth rate is
=((41.6/39.9)^(1/(5-1))-1). The growth rate is 1.05%.
now the value in 1996 = value in 1995*(1+growth rate).
And value in 1997= value in 1996 * (1+growth rate).
And so on.
For the second individual starting values are missing from 1996-2000
First I will have to find the r=growth rate of values from 1991-1995.
Than the value in 1996 =value in 1995*(1+ growth rate) and
value in 1997 =value in 1996/(1+ growth rate) and so on.
for the last indiviual values are missing from 1995-2000
if for any indiviual more than 5 values are missing do not fill that.
any code for this
