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-...
However, lumped mass matrix which reduces the computation cost could not be used combined with the 20-node elements, because the mass matrix would be non-positive definite in the case. Applying the proposed algorithm, the generalized eigenvalue problem with non-positive definite mass matrix can ...
Then, this is a covariance matrix for something that is like a multivariate normal. However, this way of creating a matrix results in a NON-positive definite matrix. Is there a way to create a covariance matrix structure based on an adjacency matrix based on putting a ...
I'm running a growth curve model. My fit statistics are fine and my intercept and slope make sense given the data. However, I keep getting an error message that the theta matrix is non-positive definite. I've checked to see if the observed variables are collinear (I ran a regression wi...
