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。
"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...
I want to run a factor analysis in SPSS for Windows. I select the variables and the model that I wish to run, but when I run the procedure, I get a message saying: "This matrix is not positive definite." I do not get any meaningful output as well,
Hessian matrix is not positive definite. J = M'*M; r = [beta;alpha]; c = M'*r; [L,p] = chol(J,'lower'); Linv = inv(L); opt = mpcqpsolverOptions; [z,status] = mpcqpsolver(Linv,c,[],zeros(0,1),[],zeros(0,1),false(0,1),opt); ...

泊松比由你给出的数值计算得出负值，是不是不同软件设置不同啊
生态学中在应用spss进行数据分析时,点击了 KMO and bartlette’s test选项,没有出现相应的KMO值和卡方统计量的值,出现了this matrix is not positive definite提示,但是还可以出现数据分析的结果,请问,这个数据的结果还可以使用吗?这个分析结果是否具有使用价值?能否能在科技论文中使用这些数据结果? 查看本题试卷 如...
