我的模型一直识别不出来,如果增加additional constraint?如下文: Result (Default model)The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 1 additional constraint.
我想请问下,我的没有错误,但是是出现The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 5 additional constraint
不过我删除了几条路径后,依然是The model is probably unidentified. In order to achieve identifiability, it will probably be necessary to impose 5 additional constraint。请问下是什么原因?
