提取协方差矩阵非线性拟合

Question

Using a JSL script, I would like to extract the covariance matrix of a nonlinear model. I have a 4PL curve. But when I request: m["Logistic 4P"]["Parameter Estimates"]["Covariance of Estimates"]["Reference"][""];

It is said that it is an outlinebox and therefore can't be converted into a Data Table, nor a matrix.

However, while right clicking on it, I can convert it in both, so it must be possible using JSL.

Any ideas?

Answer 1

好吧，最终，它找到了，如果它可以帮助某人：

m["Logistic 4P"]["Parameter Estimates"]["Covariance of Estimates"]["Reference"][1] << make into data table;
