我想计算给定日期的两个关系表之间的平均收益率
Table1 Table2
+-------------------------------+ +-------------------------------+
| ID TradeDate Amount | | ID TradeDate Yield |
+-------------------------------+ +-------------------------------+
| 1 2018/11/30 100 | | 1 2018/11/8 2.2% |
| 1 2018/11/8 101 | | 1 2018/8/8 2.1% |
| 1 2018/10/31 102 | | 1 2018/5/8 2.0% |
| 1 2018/9/30 103 | | 2 2018/9/8 1.7% |
| 2 2018/11/30 200 | | 2 2018/6/8 1.6% |
| 2 2018/10/31 203 | | 2 2018/3/8 1.5% |
| 2 2018/9/30 205 | | 3 2018/10/20 1.7% |
| 3 2018/11/30 300 | | 3 2018/7/20 1.6% |
| 3 2018/10/31 300 | | 3 2018/4/20 1.6% |
| 3 2018/9/30 300 | +-------------------------------+
+-------------------------------+
我创建一个名为“ DateList”的表,并使用切片器选择指定的日期。
截屏日期列表。
我想获得以下结果:
as of *11/9/2018*
+-----------------------------------------------------------------+
| ID LastDate Value LatestYieldDate LastYield |
+-----------------------------------------------------------------+
| 1 2018/11/8 101 2018/11/8 2.2% |
| 2 2018/10/31 203 2018/9/8 1.7% |
| 3 2018/10/31 300 2018/10/20 1.7% |
+-----------------------------------------------------------------+
| Total 604 1.7836% |
+-----------------------------------------------------------------+
当前,我使用以下公式获得部分结果
在表1中创建2个度量
LastDate =
VAR SlicerDate = MIN(DateList[Date])
VAR MinDiff =
MINX(FILTER(ALL(Table1),Table1[ID] IN VALUES(Table1[ID])),
ABS(SlicerDate - Table1[TradeDate]))
RETURN
MINX(FILTER(ALL(Table1),Table1[ID] IN VALUES(Table1[ID])
&& ABS(SlicerDate - Table1[TradeDate]) = MinDiff),
Table1[TradeDate])
Value = CALCULATE(SUM(Table1[Amount]), FILTER(Table1, Table1[TradeDate] = [LastDate]))
在表2中创建2个度量
LastYieldDate =
VAR SlicerDate = MIN(DateList[Date])
VAR MinDiff =
MINX(FILTER(ALL(Table2),Table2[ID] IN VALUES(Table2[ID])),
ABS(SlicerDate - Table2[TradeDate]))
RETURN
MINX(FILTER(ALL(Table2),Table2[ID] IN VALUES(Table2[ID])
&& ABS(SlicerDate - Table2[TradeDate]) = MinDiff),
Table2[TradeDate])
LastYield = CALCULATE(SUM(Table2[Yield]), FILTER(Table2,
Table2[TradeDate] = [LastYieldDate]))
我不知道要计算2张桌子之间的平均收益率 这是我目前的结果。
屏幕截图当前结果。
