方差矩阵 meaning in Chinese
covariance matrix
dispersion matrix
variance matrix
Examples
- Simplified gauss - markov estimate with singular noise variance
估计在噪声方差矩阵不可逆时的化简 - Estimation of covariance matrices
协方差矩阵的估计 - Covariance matrix estimation
协方差矩阵估计 - Based on the constant velocity model , the principle of how to adjust the process noise covariance matrix q is analyzed
以常速模型为基础，分析了根据机动输入来调整过程噪声协方差矩阵q的原则。 - An advantage of this method is that it can be applied when the covariance matrix of the invested projects is positive semi - definite
该方法的优点在于能够处理各投资项目之间的协方差矩阵为半正定的情形。
