当你遇到错误 "ValueError: The parameter covariance_matrix has invalid values" 时,这通常意味着你提供给某个函数或方法的协方差矩阵不符合预期的要求。为了解决这个问题,你可以按照以下步骤进行检查和调整: 检查covariance_matrix参数的值: 确保covariance_matrix中不包含任何无效或异常值,如NaN(非数字)或Inf(无穷...

In case of data points having zero mean, then the covariance matrix can be calculated by employing a semi-definite matrix, i.e. XXT as follows: In simple terms, the covariance matrix for two-dimensional data can be represented as follows: Here: C represents covariance matrix (x,x) and (...
Briefly, we first identified the seed regions of each network and then carried out PLS regression with the GM density of the voxels in the GM map to obtain the voxel group with the strongest correlation with the seed regions (Fig. 1A). The between-participant correlation matrix of the ...
