Z= zscore(X,flag,vecdim)standardizesXover the dimensions specified by the vectorvecdim. For example, ifXis a matrix, thenzscore(X,0,[1 2])is equivalent tozscore(X,0,'all')because every element of a matrix is contained in the array slice defined by dimensions 1 and 2. example [Z,...
Az-scoreand at scoreare both used inhypothesis testing. Few topics inelementary statisticscause more confusion to students than deciding when to use the z-score and when to use the t score. Generally, in elementary stats andAP stats, you’ll use a z-score in testing more often than ...

在Python 中,scipy.stats.zscore()函数可以用来计算一组数据的标准化系数。标准化系数可以用来衡量数据点在一个数据集中的相对位置。 具体来说,标准化系数是将每个数据点减去数据的平均值,然后除以数据的标准差得到的值。这样就可以得到一组具有均值为零且标准差为一的数据。
