双语版 TED-Ed 演讲精选 The electron will behave more like a wave than a particle, with its position described by probability distributions that you'll have to imagine. 电子的行为不像粒子,而更像是波,想像它出现的位置以机率分布。 可汗学院:统计学(视频版) This is the variance of your original probability distribution. 这是原始概率分布的方差。 可汗学院:统计学(视频版) And let me draw its probability distribution. 让我画出它的概率分布。 可汗学院:生物化学 All you can know is a probability distribution of where it is likely to be. 您所知道的只是它可能所在位置的概率分布。 经济学人 Culture He views people not as good or bad, but as " probability distributions" around a mean. 他认为人不是好是坏,而是围绕平均值的“概率分布”。 a student's guide I discuss why a likelihood is different to a probability distribution in basic inference. 我将讨论在基本推理中为什么可能性与概率分布不同。 a student's guide And I focus on the methods which are required to independently sample from a probability distribution. 我主要讲从概率分布中独立抽样所需要的方法。 a student's guide Really the typical way in which it stated is in terms of probability distribution. 它最典型的表述方式是概率分布。 a student's guide So what can we do? Well, it turns out that one way of understanding a probability distribution. 那么我们能做什么呢 这是理解概率分布的一种方法。 可汗学院:统计学(视频版) The probability of getting any x, and it's a class of probability distribution functions. 得到任意x的概率,是一类概率分布函数。 可汗学院:统计学(视频版) And this also applies to the discrete probability distributions. 这也适用于离散概率分布。 可汗学院:统计学(视频版) What I have just drawn is a binomial probability distribution. 我刚才画的是二项式概率分布。 可汗学院:统计学(视频版) This is a discreet probability distribution of me making, in this case, k shots out of 6. 这是我做出的谨慎概率分布,在这种情况下,6 次中有 k 次。 可汗学院:统计学(视频版) So this is the sum over the entire probability distribution, and so that is going to be equal to 1. 所以这是整个概率分布的总和,所以它等于 1。 a student's guide And this, together with some of the other difficulties of dealing with high dimensional probabilities distributions, mean that. 这个 加上其他一些处理高维概率分布的困难 意味着。 可汗学院:统计学(视频版) It's a particular instance of the binomial probability distribution. 这是二项式概率分布的一个特例。 可汗学院:统计学(视频版) So that's my probability distribution function. 这就是我的概率分布函数。 可汗学院:统计学(视频版) Well, you can look at the probability distribution, the discreet probability distribution. 嗯,你可以看看概率分布,离散概率分布。 可汗学院:统计学(视频版) But that's my discrete probability distribution function. 但那是我的离散概率分布函数。 可汗学院:统计学(视频版) It isn't true for any random variable, X. Only true for random variable, X, whose probability distribution is the binomial distribution. 它不适用于任何随机变量 X。仅适用于概率分布为二项分布的随机变量 X。
英语百科
Probability distribution![]() ![]() ![]() In probability and statistics, a probability distribution assigns a probability to each measurable subset of the possible outcomes of a random experiment, survey, or procedure of statistical inference. Examples are found in experiments whose sample space is non-numerical, where the distribution would be a categorical distribution; experiments whose sample space is encoded by discrete random variables, where the distribution can be specified by a probability mass function; and experiments with sample spaces encoded by continuous random variables, where the distribution can be specified by a probability density function. More complex experiments, such as those involving stochastic processes defined in continuous time, may demand the use of more general probability measures. |
