Details
The possible values of ties
and their effect relative to the value of who
are:
binary
or 1
for binary ties: 1
if there is at least one common manager or owner, 0
otherwise.
naive
, or 2
for 'naively' valued ties indicating the number of common managers and owners.
share
or 3
(the default) for 'normalised' tie values. The actual value depends on combining
:
for
sum
(the default), the sum of the share ofi
's owners who are also amongstj
's owners and the share ofi
's managers who are also amongstj
's managers (normalised to 2);for
mean
oravg
, the mean of the share ofi
's owners who are also amongstj
's owners and the share ofi
's managers who are also amongstj
's managers (normalised to 1);for
max
, the maximum between the share ofi
's owners who are also amongstj
's owners and the share ofi
's managers who are also amongstj
's managers (normalised to 1);for
min
, the minimum between the share ofi
's owners who are also amongstj
's owners and the share ofi
's managers who are also amongstj
's managers (normalised to 1);
Value
A matrix object of class financial_matrix
(possibly using the Matrix
package)
