想请教一下楼主和知道的老师们,我用R中waldtest跑出来的都是警告:
In addition: Warning messages:
1: In modelUpdate(objects[[i - 1]], objects[[i]]) :
for numeric model specifications all values have to be >=1
2: In modelUpdate(objects[[i - 1]], objects[[i]]) :
more terms specified than existent in the model: 1.277459
请问知道如何处理吗?
