Parameter estimation on a systematic sample
syst.estimator(
N,
sample,
estimator = c("total", "mean", "proportion", "class total"),
method = c("srs", "strata", "syst"),
alpha,
data,
t
)
N |
Population size |
sample |
Vector containing the systematic sample |
estimator |
Estimator to compute. Can be one of "total", "mean", "proportion", "class total". Default is "total". |
method |
Method of variance estimation. Can be one of "srs", "strata", "syst". |
alpha |
Optional value to calculate estimation error and build 1-alpha confidence interval. |
data |
Population data. |
t |
Number of systematic samples to take with interpenetrating samples method. |
Variance estimation has no direct formula in systematic sampling, thus estimation method must be done. Refer to syst.intracorr
and syst.intercorr
functions details for more information.
"syst" method uses interpenetrating samples method in which t systematic samples of size=\frac{n}{t}
are taken to estimate. \frac{n}{t}
must be even.
By choosing the start at random for all the samples they can be considered random taken. With this method population data and t must be given.
