Fits the model to the unbiased sample covariance matrix (rather than the maximum likelihood estimate). In other words, the sample covariance matrix is composed of sums of squares and cross products divided by N - 1 (rather than by N).

Default
Amos fits the model to the biased sample covariance matrix, which is the maximum likelihood estimate, unless you use the FitUnbiasedMoments method.
Remarks
FitUnbiasedMoments and InputUnbiasedMoments have different effects. InputUnbiasedMoments specifies that any sample covariance matrix that is read from a data file is an unbiased estimate. FitUnbiasedMoments, on the other hand, tells Amos to fit the model to the sample covariance matrix ( in the User's Guide, Appendices A and B) that is an unbiased estimate.
