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
你好，很高兴为解答 “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...
aIf convergence is not achieved, calculate the values of the tear variables for the next iteration and go back to step 3. 如果汇合没有达到,计算泪花可变物的价值为下叠代并且去回到第3步。[translate]
Hello! 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 estim...
In this FAQ, we assume that you are not getting the “convergence not achieved” error message becausextgeehas performed the maximum number of iterations. If that limit is being reached, you should try specifying a higher number in theiterate()option ofxtgeeor increase the maximum number of ...
aExcept as permitted elsewhere under this Agreement 除了如到别处在这项协议下许可[translate] athe value of Uo is updated and a new value is calculated until convergence is achieved with the pre-specified tolerance. Uo的价值更新,并且新的价值被计算,直到汇合达到以被预先指定的容忍。[translate]...
