Dear statalister,
I have the following stata output:
> esenti = 0
Variable | Obs Mean Std. Dev. Min Max
______________________________________________________
nnotti | 1032 4.545543 4.936243 1 80
-> esenti = 1
Variable | Obs Mean Std. Dev. Min Max
__________________________________________________________
nnotti | 3125 9.78528 12.73163 1 90
"Esenti" is a dummy variable that indicates if a person copayment free
or not. "nnotti" are the numbers of days spent in a hospital.
So, the total number of nights, are 1032 (Obs) x 4.545543 + 3125 X
9.78528 = 35270
I wish to calculate the proportion of nights spent by esenti=1 out of
total nights. I compute simply this proportion, but It's just a sample
proportion. Is it meaningful to randomly replicate my sample 1000
times and compute my proportion for each of these samples? It allows
me to have a range of values of my proportion and not only a single
sample value. I think this should be bootstrapping, but I don't have a
deep knowledge about this argument. If yes, how to do it on stata?
I appreciate any advice or comment.
Many thanks,
Vincenzo
