Scott's Coefficient of Agreement

Use Scott's coefficient of agreement to measure agreement for two nominal-scaled variables, where at least one of the variables is not a two-point scale, no distinction is made between a dependent and an independent variable, and you want a penalty if the variables do not have the same distribution. The MicrOsiris command INDEX_RELIABILITY computes this statistic along with several other measurements of reliability, including Cronbach's alpha.

The MicrOsiris command ITEM_ANALYSIS computes other measures of reliability, including the Kuder-Richardson equation for scale relaibility.
