regressive independence; independence; conditional independence
条件回归独立性是指给定随机变量Z=z时，随机变量X的条件期望E（X／y，z）不依赖于y．本文讨论了条件回归独立性与条件随机独立性之间的关系，找到了两者等价的充分必要条件．
條件迴歸獨立性是指給定隨機變量Z=z時，隨機變量X的條件期望E（X／y，z）不依賴于y．本文討論瞭條件迴歸獨立性與條件隨機獨立性之間的關繫，找到瞭兩者等價的充分必要條件．

For a given random variable , the conditional expectation of the random variable is. If dose not depend on then we call and have the conditional regressive independence relationship. This paper discuss the relationship between conditional return independence and conditional independence.
