使用的是10年的600家上市公司数据,做门限回归,输入代码xtptm llev ta llroaa llapp lomm taxx rtt icr liq gdp go bd mp, rx(llroaa) thrvar(year) iters(1000) trim(0.05) grid(100) regime(2)
然后出现了
threshold_bs(): 3200 conformability error ptm(): - function returned error
<istmt>: - function returned error
具体错误是
error . . . . . . . . . . . . . . . . . . . . . . . . Return code 3200
conformability error
A matrix, vector, or scalar has the wrong number of rows and/or
columns for what is required. Adding a 2 x 3 matrix to a 1 x 4
would result in this error.
还有就是结果出来很奇怪
求助大神们
