lambda: Lambdas or the weight of the peers

In Benchmarking: Benchmark and Frontier Analysis Using DEA and SFA

Lambdas or the weight of the peers

Description

The lambdas, i.e. the weight of the peers, for each firm.

Usage

lambda(object, KEEPREF = FALSE)
lambda.print(x, KEEPREF = FALSE, ...)

Arguments

object, x	A Farrell object as returned from dea et al.
KEEPREF	if TRUE then all firms are kept as reference firms even though they have all zero weights (lambda); might come handy if one needs to calculate X x lambda such that the firms in X and lambda agree. If FALSE, the default, then only weight for the peers are in the matrix lambda.
...	Optional parameters for the print method.

Details

Only returns the lambdas for firms that appear as a peer, i.e. only lambdas for firms where at least one element of the lambda is positive.

Value

The return is a matrix with the firms as rows and the peers as columns.
