楼主,我在手册里面看到“If you are loading tabular data values, select the
“Tabular Data” button. If you are loading a covariance matrix, select “Covariance Data.” Note
that if you are loading a covariance matrix, your text file should contain only the lower half of
the matrix, as Tetrad will not accept an entire matrix.”,是不是使用协方差矩阵也可以呀?我们用的这个tabular data是什么意思啊,我看手册没看懂,求指教
