标题： Observational evidence for stochastic biasing

摘要： 我们证明，在拉斯卡姆帕纳斯红移巡天（LCRS）中的星系密度无法与潜在的质量分布完全相关，因为各种星系子种群彼此之间即使考虑到光子噪声也并非完全相关。 这排除了简单线性偏差的假设，并表明最近提出的随机偏差框架对于建模实际数据是必要的。 显示英文摘要

摘要： We show that the galaxy density in the Las Campanas Redshift Survey (LCRS) cannot be perfectly correlated with the underlying mass distribution since various galaxy subpopulations are not perfectly correlated with each other, even taking shot noise into account. This rules out the hypothesis of simple linear biasing, and suggests that the recently proposed stochastic biasing framework is necessary for modeling actual data.
