unknown function sqr() r(133); . display sqrt(10) 3.1622777 或者,试试用 twoway function 画点图。 . twoway function clip(x, 0.2, 0.8) . twoway function chop(x, 1), ra(0 10) 第三,在代码书写时手动布局。逗号后和运算符周围的空格通常会使代码更具可读性。 gen x=1*2+3/4-sqrt(5)...

f(Ci) is a function of the municipality's location. The functional form of f(Ci) is unknown and thus I approximate it by two forms of polynomial to control smooth functions of locations. Random effect αi and idiosyncratic error term εit is assumed to follow the normal distribution and...
Bayesian analysis is a statistical analysis that answers research questions about unknown parameters using probability statements. For example, what is the probability that the average male height is between 70 and 80 inches or that the average female height is between 60 and 70 inches? Or, what ...
在已有的Stata中,可用命令var来估计VAR模型,而后续命令则包括:使用fcast进行 “动态预测”(dynamic forecast),以及使用irf估计 “脉冲响应函数”(impulse response function,简记 IRF)与 “预测误差方差分解”(forecast error variance decomposition,简记 FEVD)。

My main argument is that user-written Stata packages are thesource of learningadvanced Stata programming. In general, any program - whether it is written by Stata staff or a Stata user - intends to solve a problem or facilitate a task. While other users can get benefit from using the progr...
