Sensitivity criterion with which triads are marked as
unbalanced. A bigger values willl lead to less imbalanced
triads. The default is 
The function calculates the conflict measure as devised by Bassler et al.
(1992). It is an improved version of the ideas by Slade and Sheehan (1979)
that have been implemented in the function indexConflict1
. The
new approach also takes into account the magnitude of the correlations in a
traid to assess whether it is balanced or imbalanced. As a result, small
correlations that are psychologically meaningless are considered accordingly.
Also, correlations with a small magnitude, i. e. near zero, which may be
positive or negative due to chance alone will no longer distort the measure
(Bassler et al., 1992).
Description of the balance / imbalance assessment:
Order correlations of the triad by absolute magnitude, so that r_max > r_mdn > r_min.
Apply Fisher's Ztransformation and devision by 3 to yield values between 1 and 1
Check whether the triad is balanced by assessing if the following relation holds:
If Z_max x Z_mdn > 0, the triad is balanced if Z_{max} Z_{mdn}  Z_{min} <= crit Z_max x Z_mdn  Z_min <= crit .
If Z_max x Z_mdn < 0, the triad is balanced if Z_{min}  Z_{max} Z_{mdn} <= crit Z_min  Z_max x Z_mdn <= crit .
I am a bit suspicious about step 2 from above. To devide by 3 appears pretty arbitrary.
The r for a zvalues of 3 is 0.9950548 and not 1.
The r for 4 is 0.9993293. Hence, why not a value of 4, 5, or 6?
Denoting the value to devide by with a
, the relation for the
first case translates into a Z_{max} Z_{mdn} <= \frac{crit}{a} + Z_{min}
a x Z_max x Z_mdn =< crit/a + Z_min. This shows that a bigger value of a
will make it more improbabale that the relation will hold.
