查询词典 variance analysis

Analyses of a neighbor-joining tree of identified DNA haplotypes and F values between samples, and an analysis of molecular variance revealed significant genetic differences between samples from Portugal and Taiwan, but no differentiation among the samples from Taiwan.

By the modem time series analysis method, based on the ARMA innovation model, under the linear minimum variance optimal information fusion criterion, three distributed fusion steady-state optimal Kalman filters, predictors and smoothers weighted by matrices, scalars, and diagonal matrices are presented for multisensor systems with correlated input and observation noises, and with correlated observation noises. The Lyapunov equations and formulas of computing local filtering, predicting and smoothing error variances and covariances are given, which are applied to compute optimal weights. The corresponding three distributed fusion Wiener state estimators are also presented.
