stratasize.Rd
The function stratasize
determinates the total size of stratified samples depending on type of allocation and determinated by specified precision.
stratasize(e, Nh, Sh, level = 0.95, type = 'prop')
e | positive number specifying sampling precision. |
---|---|
Nh | vector of population sizes in each stratum. |
Sh | vector of standard deviation in each stratum. |
level | coverage probability for confidence intervals. Default is |
type | type of allocation. Default is |
The function stratasize
returns a value, which is a list consisting of the components
is a list of call components: e

population sizes of every stratum, Sh
standard diviation of every stratum, method
type of allocation, level
coverage probability for confidence intervals.
