stata - 以更短的语法使用 if ()

Question

有没有办法用更简洁的语法来表达这一点

if (`avgInc' > 0) {
    loc avgIncDec = "increased"
}
else {
    loc acgIncDec = "decreased"
}

类似 InlineIf (iif) 的东西：

loc avgInc = iif((`avgInc' > 0), "increased", "decreased")

Answer 1

尝试cond

var = if cond(a="value","1","another value")

if a="value" var ="1" else var = "另一个值"

还有其他三元运算符：inrange() inlist()

Answer 2

以前的答案有帮助，cond()但包含一些小错误。

   loc avgIncDec = cond(`avginc' > 0, "increased", "decreased")

请注意，Stata 与许多其他语言一样，使用=赋值和==测试相等性。
