1. "Stata convergence not achieved" 的含义 在Stata 中,"convergence not achieved" 错误通常表示某个迭代过程(如估计模型参数)未能达到预定的收敛标准。这意味着算法在尝试找到一个合适的解决方案时未能成功,可能是因为数据特性、模型设定或计算限制等原因。 2. 可能导致该错误的原因 数据问题:数据可能存在异常值、...
广义估计方程分析结果中convergence not achieved是集合没有实现的意思
“Warning:convergence not achieved”这个就是说没有找到稳定的最优的估计值 如果有这个提示的话一般来说结果是不能使用的，需要重新正确的估计 导致这个信息的可能性很多。有些时候并不一定是你做错了什么 可以试试只用一部分数据估计，或者使用不同的起始值，或者改变最优化的方法什么的 没有什么灵丹妙...
求翻译:If convergence is not achieved, calculate the values of the tear variables for the next iteration and go back to step 3.是什么意思?待解决 悬赏分:1 - 离问题结束还有 If convergence is not achieved, calculate the values of the tear variables for the next iteration and go back to ste...

I am using MLE Heckman procedure with standard errors corrected for heteroskedasticity and clustering, with the options iterate(0) and "difficult". I get estimations but it says: "Convergence not achieved". My question is if the fact that convergence has not been achieved makes the estimations ...

I have removed the screws to use the cells for refining the mesh in the fluid spaces.However, it still shows the message that the convergence is not achieved. nHow can I know how fine my mesh should be to achieve the convergence? or can the problem be due to something other than the ...

and this does not imply that the Hessian matrix be positive definite. However, in the case of an inverse problem in which each individual positive component of the cost function is driven to 0, the global optimum is indeed achieved.
