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 ...
报错:in bootnet_correlate(data = data, corMethod = corMethod, corArgs = corArgs, : Correlation matrix is not positive definite. Owner SachaEpskamp commented Apr 14, 2023 What is the sample size? Maybe try setting caseMax lower if your sample size is too smal. The argument nCores is n...
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...
S matrix not positive definite 请问大家有遇到的吗，增加截断能，减少核数，对角化方式改为...
"The data X must have a covariance matrix that is positive definite." Could you please tell me where is the problem? Is it due to low mutual dependancy among the used variables? In addition, what I can do about it? Thank you.
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-...
