You can change the spread of the particles using either the Randomize Direction or the Randomize Vector by Cone compounds. 使用圆锥节点里的随机指向或者随机向量都可以改变粒子的散播范围。
In this paper, sufficient conditions are given for applicability of the law of the iterated logarithm for self-normalized sums of independent random vectors. 摘要本文给出了独立随机向量序列自正则和的重对数律成立的一个充分条件。
