Isn't it enough for me to extrapolate from cases that I do come up against in this life?
难道仅仅依靠我这辈子碰到的东西,不足以使我推断出来吗
In particular, a very common thing people do with data is they extrapolate.
这种错误,在数据预测时,很常见。
And once again we, our ears,hear this aggregate of sound and then we say, "Oh,it's got that,that,that,that," and we extrapolate out of that information that it is this particular chord.
然后再来听到这样的声音的聚合,然后我们可以说,“哦,到了那里,那里,那里,那里”,然后我们能够推断出这就是我们所指的那个和弦。
When you look at a random walk you have the intuitive impression that you can extrapolate it -that it doesn't look like -you can't believe it's really random, but the reason you can't is because you overweigh the probability of certain things that caught your attention.
当人们观察随机漫步序列时会有直观印象,并可以以此类推,虽然这看起来并不像...,人们不会觉得这是完全随机的,之所以如此,是因为,人们过分高估了特定事物发生的可能性,这吸引了人们的注意
And the other thing you can do is take self reports like the ones you're doing, hopefully do enough of them, and a random enough sample of the population, that you can extrapolate from that sample to the whole population, and try to estimate what people are eating in that way.
还有其他可以做的,比如大家正在做的这种个体调查,希望能把它做的充分些,如果有充足的随机样本,就可以从样本推断出,整个总体,从而推断哪类人有这样的饮食习惯
And we can just extrapolate in a straight line We before saw some examples where I had an algorithm to generate points, and we fit a curve to it, used the curve to predict future points and discovered it was nowhere close.
我们可以干脆用一条直线来描述它,我们之前看到在一些例子中,我用一个算法去生成一些点,然后用一条曲线对它进行拟合,然后用这条曲线来预测未来的点,最后却发现结果完全不对。
