NLP COPA数据集获取方式 nlparci函数 一、字符类函数 字符类函数是专门用于字符处理的函数,处理的对象可以是字符或者字符串常量,也可以是字符类型的列。 1、ASCII(c)和CHR(i) ASCII(c)函数用于返回一个字符的ASCII码,CHR(i)用于返回给出ASCII码值所对应的字符,它们具有互逆的关系。 dual是Oracle系统内部提供的一...
初值是我已经得到的优化结果 但是拟合显示local minimum 而且ci = nlparci(k_opt,residual,'Jacobian',...
You can refer to following which explains the ways to calculate the CV using nlparci function. https://www.mathworks.com/matlabcentral/answers/171048-how-can-i-get-the-cv-and-confidence-interval-for-my-parameter-estimates-from-output-of-lsqnonlin-fu Hope this helps! 댓글 수: 0 댓...
ci=nlparci(d1,residual,'jacobian',jacobian,'alpha',0.05); And I keep getting the error Cannot compute confidence intervals for complex values. If I look at the workspace, d1 and the residuals have no complex values, and just in case I've used the function...

There is a well-defined relation between the width of the confidence interval in standard errors and the percentage of observations falling within the confidence interval. To calculate the standard error, first you will need to find the confidence interval. The...
