[gong chiming]
计量经济学和
– [Josh] Well, there’s certainlya lot of overlap
统计学肯定有很多重合之处
between econometricsand statistics.
这两科目共同发展
These two disciplinesevolved together.
统计学更注重统计推断
Statisticians are mostly concernedwith statistical inference.
统计推断的难点在于
The problem of statisticalinference is how to learn
如何从更小的样本中
about some underlying population —
了解潜在总体
maybe the populationof the United States —
例如美国的总体
from a particular samplewhich is much smaller.
然后你会意识到样本有不可测性
Then you recognizethat there’s randomness
不同的样本
in your sampleand that different samples
会产生不同的结果
would produce different results.
我认为计量经济学通常或更注重
Econometricians are often –or most often I would say —
因果推论
concerned with causal inference.
我们抽样具有不可靠性
We certainly havesampling uncertainty.
我们遇到统计推断难题
We have problemsof statistical inference.
我们会尝试提取数据
We’re trying to extract statements,reliable statements
关于世界上反事实状况的可靠数据
about counterfactual states of the world —
如果世界在某种程度发生了改变 会怎样?
what would happen if the worldwere changed in some way?
单独的数据能告诉我们的东西有限
And there’s a limitto what data alone can tell us
我们需要依靠一套工具和建模法
so we rely on a set of toolsand modeling methods
去了解基础的未知事物 以及
in an effort to kind of learnthis fundamentally unknowable thing,
在平行宇宙和世界反事实状态将发生什么
what would happen in a parallel universe or a counterfactual state of the world.
