WebOct 11, 2024 · 其实除了提示“convergence not achieved”，模型结果（包括显著性、系数的正负号）都很不错的。这种情况下，是不是只要提示“convergence not achieved”模型结果就不能用了？还是说也可以用？ 2.如何在type(time)的条件下实现收敛，也就是不出现“convergence not achieved”。 WebThis is a very serious problem. In general these results should not be used as they usually suffer from very low robustness and display butterfly effect.In other words, the parameters can change very quickly as new data flows into the model and the confidence intervals of the parameters may be so huge as to show that they are statistically insignificant.
