"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...

IS NOT POSITIVE DEFINITE. THIS COULD INDICATE A NEGATIVE VARIANCE/ RESIDUAL VARIANCE FOR A LATENT VARIABLE, A CORRELATION GREATER OR EQUAL TO ONE BETWEEN TWO LATENT VARIABLES, OR A LINEAR DEPENDENCY AMONG MORE THAN TWO LATENT VARIABLES. CHECK THE TECH4 OUTPUT FOR MORE INFORMATION. ...
Besides, it is difficult to check positive definiteness for a large matrix, but usually not for the small ones. See Chapter 8 for an important example. (2) A symmetric positive definite matrix has n eigenvalues which are all real positive numbers. (3) The determinant of a symmetric positive...
Correlation matrix is not positive definite. At first, I thought the sample size might be less than the number of symptoms, but when I adjusted the number of symptoms (25) to be less than the sample size (26), the error still occurred, by the way, there were still a very small numbe...
