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 Z-transformation 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 .
NOTE: (MH) I am a bit suspicious about step 2. To devide by 3 appears pretty arbitrary.
The r for a z-values 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.
