Dear fellows !
I want to add a new column right beside f values :
# from first row to 20th row I want to divide f - value through 10
# from 21th row to 29th row I want to divide f-value through 23
and so on .........................
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I use until now :
. contract z1,freq(n) ' z1 is a variable which is to be scrutinized very
exactly
* z1 is the counted value in dosis interval
. gen N = sum(n)
. gen f = n/N[_N] * 100 f.... percentage
. gen F = sum(f) F... cumulative
. gen F100 = 100 - F F100 ... 100 -cumulative
. tabdisp z1,cellvar(n f F F100)
--------------------------------------------------------------
z1 | Frequency f F F100
