Summarizing the Allocation
Description
A helper function that returns a simple data.frame
with summary of the
allocation as returned by the opt()
or optcost()
. See the illustrate
example below.
Usage
asummary(x, A, m = NULL, M = NULL)

Value
A data.frame
with as many rows as number of strata H
+ 1,
and up to 7 variables. A single row corresponds to a given stratum
h \in \{1,\ldots,H\}
, whilst the last row contains sums of all of the
numerical values from the above rows (wherever feasible).
Summary table has the following columns (* indicates that the column may
not be present):
- A
population constant
A_h
- m*
lower bound imposed on sample size in stratum
- M*
upper bound imposed on sample size in stratum
- allocation
sample size for a given stratum
- take_min*
indication whether the allocation is of
take-min
type, i.e.x_h = m_h
- take_max*
indication whether the allocation is of
take-max
type, i.e.x_h = M_h
- take_Neyman
indication whether the allocation is of
take-Neyman
type, i.e.m_h < x_h < M_h
