wop calculates the contribution or weight of partitions for the pooled solution parameters of consistency and coverage for the conservative or parsimonious solution.

wop(dataset, units, time, cond, out, n_cut, incl_cut, solution, amb_selector)

Arguments

dataset

Calibrated pooled dataset for partitioning and minimization of pooled solution.

units

Units that define the within-dimension of data (time series).

time

Periods that define the between-dimension of data (cross sections).

cond

Conditions used for the pooled analysis.

out

Outcome used for the pooled analysis.

n_cut

Frequency cut-off for designating truth table rows as observed in the pooled analysis.

incl_cut

Inclusion cut-off for designating truth table rows as consistent in the pooled analysis.

solution

A character specifying the type of solution that should be derived. C produces the conservative (or complex) solution, P the parsimonious solution. See wop_inter for deriving intermediate solution.

amb_selector

Numerical value for selecting a single model in the presence of model ambiguity. Models are numbered according to their order produced by minimize by the QCA package.

Value

A dataframe with information about the weight of the partitions with the following columns:

  • type: The type of the partition. between stands for cross-sections; within stands for time series. pooled stands information about the pooled data.

  • partition: Type of partition. For between-dimension, the unit identifiers are listed (argument units). For the within-dimension, the time identifiers are listed (argument time). The entry is - for the pooled data.

  • denom_cons: Denominator of the consistency formula. It is the sum over the cases' membership in the solution.

  • num_cons: Numerator of the consistency formula. It is the sum over the minimum of the cases' membership in the solution and the outcome.

  • denom_cov: Denominator of the coverage formula. It is the sum over the cases' membership in the outcome.

  • num_cov: Numerator of the coverage formula. It is the sum over the minimum of the cases' membership in the solution and the outcome. (identical to num_cons)
