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。
WARNING: THE LATENT VARIABLE COVARIANCE MATRIX (PSI) IN CLASS 1 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 VARIAB...

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...

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...
