Neyman Allocation
Neyman allocation is a sample allocation method that may be used with stratified
samples. The purpose of the method is to maximize survey precision, given a
fixed sample size. With Neyman allocation, the "best" sample size for stratum h
would be:
nh = n * ( Nh * Sh ) / [ Σ ( Ni * Si ) ]
where nh is the sample size for stratum h, n is total sample
size, Nh is the population size for stratum h, and Sh
is the standard deviation of stratum h.
Neyman allocation is actually a special case of
optimal allocation
.
