刚装Clementine 12看了几天, 在历史数据库抽取了一组数据,试图求解是否存在某种量价关系。
用C&RT模型树建模,得出以下结果。请专业人士帮助通俗解读,以便我理解实际意思。
PRICE <= 63.280 [ 平均:57.436, 效应: 22.988 ] => 57.436 (1,478)
PRICE > 63.280 [ 平均:26.281, 效应: -8.167 ] (4,160)
PRICE <= 89.103 [ 平均:36.449, 效应: 10.168 ] (1,716)
PRICE <= 87.820 [ 平均:30.865, 效应: -5.584 ] (1,659)
PRICE <= 80.415 [ 平均:17.52, 效应: -13.345 ] (1,207)
PRICE <= 66.581 [ 平均:6.965, 效应: -10.554 ] => 6.965 (391)
PRICE > 66.581 [ 平均:22.577, 效应: 5.057 ] => 22.577 (816)
PRICE > 80.415 [ 平均:66.501, 效应: 35.636 ] => 66.501 (452)
PRICE > 87.820 [ 平均:198.981, 效应: 162.532 ] => 198.981 (57)
PRICE > 89.103 [ 平均:19.142, 效应: -7.139 ] (2,444)
PRICE <= 188.248 [ 平均:20.826, 效应: 1.685 ] (2,171)
PRICE <= 89.863 [ 平均:6.776, 效应: -14.051 ] => 6.776 (150)
PRICE > 89.863 [ 平均:21.869, 效应: 1.043 ] => 21.869 (2,021)
PRICE > 188.248 [ 平均:5.744, 效应: -13.397 ] (273)
PRICE <= 263.960 [ 平均:8.503, 效应: 2.758 ] => 8.503 (158)
PRICE > 263.960 [ 平均:1.954, 效应: -3.79 ] => 1.954 (115)
