semis assuming thatPriceis a latent variable; if that was the case, the model wouldn't be identified. We need to add the optionnocapslatent, sosemwill treat all variables as observed by default. When thenocapslatentoption is present, thelatent()option can be used to tell Stata which variab...

option rho not allowed ~有跑出表來 也有dw值 請問一下這是正常的嗎??? 後來我留一家公司做為測試.結果就沒這樣的問題.. 所以想請教您的是 1.stata跑時間序列資料時,是不是不能太多樣本公司 2.如果要跑很多樣本公司 那麼該怎麼處理 ><"不好意思.由於在趕一篇要投稿的論文 ...
The selection part must contain a variable that is different from the variables in the outcome equations. If you use the twostage option, the vce(cluster clustervar robust), weights and score() options are not allowed.

接下来的是对 x 进行 permute 500 次【命令中的 permute x 和 option 里面的 reps(500) 】,每次都是对同一家公司不同年份进行 permute 【option 里面的 strata(code)】,这样就不会把 A 公司的数据给了 B 公司(不然就搞得和安慰剂检验差不多了)。最终的目的是对 x 的系数进行估计【命令中的 beta=_b[...

Modelnoconstant; see [R] estimation options. hascons indicates that a user-defined constant or its equivalent is specified among the independent variables in indepvars. Some caution is recommended when specifying this option, as resulting estimates may not be as accurate as they otherwise would be...
In fact, all log links can be modeled with the p(0) option. Hence, to model a simple default lognormal regression, use the following command: . glmp depvar varlist, f(gau) p(0) ;Bernoulli and binomial distributions have a log( =(1 )) canonical link which cannot be modeled using ...
