honestdidhas built-in support for the user-writtenparallelpackage (latest stable version required).parallel(#)can be specified as an option with#signifying the number of cores (parallel processes; default 4). Each core processes anMin parallel. For example, ...
crosssectional() is a required option but can be substituted by nocrosssectional. If cr(..., cr_lags()) is used, then the global option cr_lags() (see below) is ignored. rcce[(criterion(er/gr) scale npc(integer))] implements the regularized CCE estimator from Juodis (2022). ...
*absorb(absvars)is required. + indicates a recommended or important option. indepvars,endogvarsandiv_varsmay contain factor variables; seefvvarlist. all the regression variables may contain time-series operators; seetsvarlist. fweights,aweights andpweights are allowed; seeweight. ...
Option std for the factor extraction from standardized variables requires at least Stata 16.1 with c(born date) ≥ 30jun2020. In earlier Stata versions, the command can still be used but with reduced functionality. To absorb fixed effects, xtivdfreg requires reghdfe (Sergio Correia, 2014, ...
absorb() may not be specified with the vce(hc2) option. nosigmau is part of StataNow. It prevents the computation of . When absorb(varlist) is specified, the estimation of requires an iterative search. If is not of interest, you may specify nosigmau to save computational time. noui...
这个命令用来实现堆叠DID算法,因为 ssc 上发布的太难用了,所以自己做了一个。 1. 堆叠DID模型设定 这里不讲述原理,只讲述设定。以下述数据集为例: 一共有四个样本,每个样本的政策冲击年份不同,样本1是1999年(always treated),样本2是2002年(pre-treated),样本3是2004年(post-treated),样本4没有受到政策冲击...
If you want to runpredictafterward but don't particularly care about the names of each fixed effect, use thesavefesuboption. This will delete all preexisting variables matching__hdfe*__and create new ones as required. Example:reghdfe price weight, absorb(turn trunk, savefe). ...
If it’s too much grading for the TAs to grade term papers I will either grade enough personally to absorb the excess hours or choose another assignment. Assigning group work cuts down the number of papers but it doesn’t really reduce the total instructional hours. I’m also not saying ...
The '@' indicating the presence of a plausible value variable is required. This example shows that the names of statistics to be mentioned in this option might differ from those written in the outfile dataset. The starting '_' appearing in the outfile dataset for dummy variables must be ...
