Arguments

x,

Object of class other than "6DF_summary" or dataframe

weights,

numeric vector of weights used to form the GCI linear combination

means,

numeric vector of mean values for the 6 degree of freedom approximation, subtracted away before calculation of GCI

stddevs,

numeric vector of standard deviations for each of the values within the 6 degree of freedom approximation, used for scaling before GCI calculation
