“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...
3. 解决 "convergence not achieved" 错误的建议方法 检查数据: 清理数据,去除异常值和缺失值。 检查数据的分布和范围,确保它们符合模型的假设。 调整模型: 简化模型,减少参数数量。 尝试不同的模型设定,如改变链接函数或分布类型。 调整初始值,为迭代过程提供一个更好的起点。 增加计算资源: 如果可能,使用更...
广义估计方程分析结果中convergence not achieved是集合没有实现的意思
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 step 3.问题补充:匿名 2013-05-23 12:21:38 如果没有达到收敛,计算为下一次迭代的泪变量的值,并返回到步骤3。 匿名 2013-05-23 12:23:18 ...
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...
I initially used a -tobit- model. However my concerns about non-normality and heteroskedasticity meant I switched to -clad-. However when I run the same regressions as I did with my tobit model, I now receive the error message "convergence not achieved". I have systematically removed each ...
Dear all, I am modeling a bridge consists of two different materials (Steel and Bamboo) and two different type of contacts between component (Bonded and Frictional). The bridge is fix supported at both ends and a load is applied at the center of bridge.
High grades in primary schools and junior high schools of first-year writing characteristics of teaching materials should be balanced with each other, materials can be achieved good convergence. Since China's English teaching in primary schools is not universal, and development is still very unbalan...
