Density For Distance Between Two Points In Rectangles
两点之间的距离在矩形的密度
译者:生物统计家园网 机器人LoveR
描述----------Description----------
This evaluates the density for the distance between two points, each distribution uniformly and independently in rectangles. The rectangles are congruent and lie on a lattice. Three special cases exist, when the two rectangles coincide, when the two rectangles lie on the same row (or column) of the lattice and when the
这计算两点之间的距离,每个分布均匀地和独立地在矩形的密度。的矩形是一致的和躺在一个格子。存在三种特殊情况,当两个矩形重合,当两个矩形趴在相同的行(或列)的晶格中,并且当
