考虑以下示例代码: clear set obs 20 generate t = 2000 + _n tsset t, yearly tsappend, last(2025) tsfmt(ty) 这将崩溃,并显示以下错误: unknown function ty() r(133); 但是,根据的说法,应该支持tsfmt选项的ty参数(即使在Stata中实际上没有ty()函数)。 我知道我可以通过一些数学运算和tsapp...
foreach vname in y1 y2 y3 { (确定y变量组vname) reg `vname' x1 x2 x3 (将y变量组中的各个变量与诸x变量进行回归分析,注意vname的标点符号) } 上式等价于: mvreg y1 y2 y3 = x1 x2 x3 reg3命令: (1)简单用法: reg3 (y1 = x1 x2 x3) (y2 = x1 x3 x4) (y3 = x1 x2 x5) ...
1、生成一个自变量和一个因变量。2、点击Statistics|linear model and related|linear regression菜单。3、在弹出的regress中设置相关变量，然后再点确定。4、在结果界面中，_cons为.5205279表示回归截距，说明回归方程具有统计学意义。R-squared和Adj R-squared分别为0.9905和0.9893，说明回归方程拟合效果...

with Stata and should have experience with programming tools such as local macros (local) and loops (foreach,forvalues). They should also know in principle what an ado-file is. Reading chapter 12 of Kohler and Kreuter'sData Analysis Using Statawould provide excellent preparation for participants...
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...
