With the data above, I would like to summarise price and generate its sd. Forexample:
I summarise price in 1/2 and save the sd at 2,
then I summarise price in 2/3 and save sd at 3
hen I summarise price in 3/4 and save sd at 4
.......all the way to the end

Try the following code: gen id = _n

rangestat (count) price (mean)price (sd) price , interval( id -1 0)

Try the following code: gen id = _n

rangestat (count) price (mean)price (sd) price , interval( id -1 0)

Thank you Itesh,
This is what has finally worked:

gen id = _n

rangestat (count) Price (mean) Price (sd) Price , interval( id -11 0)
