WebComposite M: method weighting. Allows for weighting of the contribution of each method in the composite M distribution. Values range from 0 to 1. A value of 0 removes the contribution; a value of 1 is full weighting. WebMar 14, 2024 · 可以使用 scree plot 方法来确定降维数。具体来说,我们可以计算每个主成分的方差贡献率,然后画出方差贡献率与主成分个数的关系图,找到一个拐点,该拐点对应的主成分个数就是我们要选择的降维数。
