Question

我有以下表格：

模型表

Model    State  FH

NEW-20  1   279

NEW-20  2   279

NEW-20  3   204

NEW-20  4   186

NEW-21  1   333

SA 表

Driver  Year    Scenario;

GDP 2013    Nominal

Fuel    2013    Nominal

Mili    2013    Nominal

GDP 2014    Nominal

Fuel    2014    Nominal

Mili    2014    Nominal

GDP 2015    Nominal

Fuel    2015    Nominal

UTI 表

Driver  Scenario    State        var1       var2      var3       var4      var5      var6;

GDP Nominal  1             0.0% 0.0%    0.0%    0.0%    0.0%    0.0%

GDP Strong_G     2             10.0%    12.0%   7.5%    10.0%   10.0%   0.0%

GDP Mild_D       4                  -5.0%        -8.0%  -4.0%   -10.0%  -8.0%   -2.5%

Mil Strong_D     1            -6.0% -10.0%  -6.0%   -12.0%  -10.0%  -5.0%

MIL Nominal  1             0.0% 0.0%    0.0%    0.0%    0.0%    0.0%

我想使用条件IF语句。什么是正确的语法？以下是我想要做的事情：

(IF Model.State & SA.Driver (GDP) & SA.Scenario = UTI.Driver & UTI.Scenario & UTI.State
THEN  SUMPRODUCT((1+(UTI.VAR1--VAR6));MODEL.FH)  

+

IF Model.State & SA.Driver(Fuel) & SA.Scenario = UTI.Driver & UTI.Scenario & UTI.State
THEN  SUMPRODUCT((1+(UTI.VAR1--VAR6));MODEL.FH)

+

IF Model.State & SA.Driver(Mil) & SA.Scenario = UTI.Driver & UTI.Scenario & UTI.State
THEN SUMPRODUCT((1+(UTI.VAR1--VAR6));MODEL.FH)) 

AS TOTAL

我如何在SAS中完成？

Answer 1

您似乎正在尝试使用PROC SQL？

如果是，那么您正在寻找CASE声明：

(CASE WHEN Model.State & SA.Driver (GDP) & SA.Scenario = UTI.Driver & UTI.Scenario & UTI.State
THEN  SUMPRODUCT((1+(UTI.VAR1--VAR6));MODEL.FH) ELSE 0 /* <- Insert else case here */ END

+

CASE WHEN Model.State & SA.Driver(Fuel) & SA.Scenario = UTI.Driver & UTI.Scenario & UTI.State
THEN  SUMPRODUCT((1+(UTI.VAR1--VAR6));MODEL.FH) ELSE 0 /* <- Insert else case here */


+

CASE WHEN Model.State & SA.Driver(Mil) & SA.Scenario = UTI.Driver & UTI.Scenario & UTI.State
THEN SUMPRODUCT((1+(UTI.VAR1--VAR6));MODEL.FH) ELSE 0 /* <- Insert else case here */ END)

AS TOTAL

我不认识你的代码块。你要么使用某种pseduo代码，要么使用我以前从未见过的高级SAS技术。带上一粒盐就可以了。
