"Matrix is not positive definite - the critical load may have been exceeded" warning appears while structure calculation in RSA. Usually warning is followed by calculation divergence. Possible causes Members connected to slab in one point and...
使用非正定矩阵选项:在lavaan中,可以通过设置lavaanOptions(use.nonpositive.def = TRUE)来允许使用非正定的样本协方差矩阵。但请注意,这可能会影响模型估计的准确性和稳定性。 r # 允许使用非正定的样本协方差矩阵 lavaanOptions(use.nonpositive.def = TRUE) # 然后进行模型拟合 fit <- lavaan::cfa(model ...
矩阵不是正定的。

I’m analyzing a GMM with 4 timepoints without covariates. I have a negative variance of the intercept, that is not significant (I get the warning PSI Matrix is not positive definite). 1) How can this happen, what does this mean?

THE STANDARD ERRORS OF THE MODEL PARAMETER ESTIMATES MAY NOT BE TRUSTWORTHY FOR SOME PARAMETERS DUE TO A NON-POSITIVE DEFINITE FIRST-ORDER DERIVATIVE PRODUCT MATRIX. THIS MAY BE DUE TO THE STARTING VALUES BUT MAY ALSO BE AN INDICATION OF MODEL NONIDENTIFICATION. THE CONDITION NUMBER IS 0.176D-...
