我有一个电子表格,显示每周增加和减少的百分比。我想计算在给定年份中,一周的数字比之前一周增加的次数,而且前提是前一周的增长至少为2%。
例如,在以下电子表格中,2010年的计数应为1:
Date Increase/Decrease %
12/28/2009 -3.1%
1/4/2010 1.2%
1/11/2010 2.0%
1/18/2010 2.1% (this is the one that should be counted)
1/25/2010 1.9%
2/1/2010 2.5% (don't count because previous week did not meet 2% threshold)
这是我用来计算满足百分比增长的次数的公式,但是我不确定如何添加下周必须超过前一周的条件。
=COUNTIFS($B$2:$B$7,">"&.02,$A$2:$A$7,">"&"12/31/2009,$A$2:$A$7,"<"&"1/1/2011")
答案 0 :(得分:2)
=SUMPRODUCT(-(B3:B7>B2:B6),-(B2:B6>=0.02),-(A3:A7>DATE(2009,12,31)),-(A3:A7<DATE(2011,1,1)))
或者借助BigBen的见识:
=SUMPRODUCT((B3:B7>B2:B6)*(B2:B6>=0.02)*(YEAR(A3:A7)=2010))
