I have the dea.ado file installed in the directory on which Stata operates and everything seems to be ready to work. Unfortunately, when I try to run the DEA command, this error message is the only result: lp_phase2(): 3498 No Solution at Stage 1 and Phase 2.:[DMUi=1] _dealp(...

Stata的默认图表质量还是属于上乘的（其实Stata允许二次加工，只是加工起来比较费时），尤其是跟Eviews和S...
A score of 0–10 was thus calculated using egen command in STATA and a variable consisting of three quintiles (low, medium and high) was made using xtile command STATA 14.Household factorsi. The monthly per capita consumption expenditure (MPCE) quintile was assessed using household consumption...
repeated for the 2 and 3 °C warming scenarios as well. Estimates from the regression in Supplementary Table3are used for δ. The point estimation for warming scenarios relies on the Delta Method of asymptotic approximation for large samples as implemented via the nlcom command in Stata ...

stata软件实操 在这个数据集中,因变量为Y-price,自变量为X-weight和Z- displacement。 我们对其进行回归分析 stata回归分析的命令为:reg Y X Z reg price weight displacement 我们将这个回归结果存储为m1 est store m1 那么,是否变量Z对因变量Y与自变量X之间的关系具有调节效应呢?
All of the estimations were performed via the ppml command in Stata. See http://personal.lse.ac.uk/tenreyro/lgw.html for additional information on the ppml command. Last accessed on 07/03/2019. 20 Note that Poisson PML drops observations that are perfectly predicted. 21 We also tested the...
Analysis was conducted using the metan command in Stata software (version 12.0 by Stata Press, 4905 Lakeway Drive, College Station, Texas). Heterogeneity Because this review included only observational studies, a greater level of heterogeneity was expected. We used I2 statistic to assess between-...
STATA本身有很多estimator是通过MLE方法估计的,例如logit, probit等。在这些模型之外,STATA同时提供了ML syntax来拓展可以估计maximum likelihood模型。下面我们举例子说明ML syntax的用法。 LF Estimator 当整体样本的Log likelihood可以通过每个样本点的log likelihood累加得到时,STATA认为这类模型符合线性约束(Linear Form Re...
