It i s well known that even if the sample observations are correlated and not normal, the sample mean is normal in 1arge samples. But how large is large? This question i s investigated in this paper. In particular , the relation between the rate of convergence and the correlation property...

Shape 1. The Mean The mean of the distribution of sample means is the mean of the population The mean of the distribution of sample means is called expected value of X X is an unbiased estimate of µ: on average, the sample mean produces a value that exactly matches the population ...
Hi. I want to get a distribution of sample mean. But I just can get sample mean itself, not the distribution. e.g. テーマコピー a = rand(5,1) abar = mean(a) You know, in that case, abar shows just one number. How do I get a distribution of it?1...
mean=平均值 proportion=比例 sampling distribution of the sample mean 样本均值抽样分布 样本均值的抽样分布即所有样本均值的可能取值形成的概率分布。例如，某高校大一年级参加英语四级考试的人数为6000人，为了研究这6000人的平均考分，欲从中随机抽取500人组成样本进行观察。若逐一抽取全部可能样本，并计算...
来估计总体标准差。 方法二:使用bootstrap标准误估计总体标准差 过程 从总体中抽取一个大小为50的样本。 对该样本进行1000次bootstrap抽样(即从这个样本中有放回地抽取新的样本,每个样本的大小仍然为50)。 对每个bootstrap样本计算均值,因此我们得到1000个均值。 计算这1000个均值的标准差,这个标准差就是bootstrap标...
