The ADX Interface incorrectly reports the coded coefficients for a 2-level design when using a -1 1 coding scheme as one-half the values of the uncoded coefficients. This problem only occurs when using -1 1 coding scheme for the uncoded and coded levels for a variable in a 2-level design.

The ADX Interface should provide the same estimates for the coded and uncoded predictive equations when using -1 1 coding scheme in 2-level designs. Note that the correct coefficients are reported under the coded levels reported under the predictive model.
