Analytical study of performance of linear discriminant analysis in stochastic settings

作者:

Highlights:

• We consider the true error of linear discriminant analysis (LDA) for non-i.i.d data.

• The first and second moments of true error for univariate LDA are characterized.

• The classification performance (CP) for non-i.i.d. data is compared to i.i.d. setting.

• As an application, we consider auto-regressive (AR) or moving-average (MA) models.

• We find ranges of AR/MA coefficients that have incremental or decremental effect on CP.
