unbiased variance

基本解釋

For the measurement error model, unbiased variance estimate of latent variable is not all non-negative.
本文研究了測量誤差模型中方差的估計問題。
In the sense of linear unbiased minimum variance estimation, a global optimal recursive state estimation algorithm for this discretized linear system is proposed.
在線性無偏最小方差估計準(zhǔn)則下，推導(dǎo)出了該離散化后所得系統(tǒng)的全局最優(yōu)遞推狀態(tài)估計算法。
Based on linear unbiased minimum variance estimation theory, a fusion algorithm which fused the state vector of nonlinear systems with dissimilar sensors with arbitrary correlated noises is developed.
基于線性無偏最小方差估計理論，提出了一種任意相關(guān)噪聲異類傳感器非線性系統(tǒng)狀態(tài)矢量融合算法。

They divide by n-1 to make it an unbiased estimator of the population variance, but I'm just going to show it in a simple way here.
當(dāng)除以n-1表示的是對總體的,無偏估計,我在這里只是說的簡單一點
