错误:数组下标超出范围i + 2年

我有一个如下所示的数据集:

ID      2017    2018    2019    2020

2017    30      24      20      18
2018    30      24      20      18
2019    30      24      20      18
2020    30      24      20      18

我希望基于一些输入创建一个数组:

%let FixedorFloating = '1 or 0';
%let Repricingfrequency = n Years;
%let LastRepricingDate = 'Date'n;

数组标准是如果ID = Year + 2i则flag = 1

e.g。

ID = 2017 then flag =1 for Years 2017 and 2019, 0 otherwise

ID = 2018 then flag = 1 for Years 2018 and 2020, 0 otherwise

ID = 2019 then flag = 1 for Year 2019 , 0 otherwise

ID = 2020 then flag = 1 for year 2020, 0 otherwise

我的代码目前,我遇到了第i + 2年的问题(以红色突出显示),但是一年(i)工作正常。

data ReferenceRateContract;
    set refratecontract;

 *arrays for years and flags;
     array _year(2017:2022) year2017-year2022;
     array _flag(2017:2022) flag2017-flag2022;

*循环数组;

if &FixedorFloating=1

    then do i=&dateoflastrepricing to hbound(_year);

    /*check if year matches year in variable name*/

    if put(ID, 4.) = compress(vname(_year(i)),, 'kd') 
        then _flag(i)=1;

    else _flag(i)=0;

end;

else if &fixedorfloating=0

    then do i=&dateoflastrepricing to hbound(_year);

    if put(ID, 4.) = compress(vname(_year(i)),, 'kd') 
        then _flag(i)=1;

    else if put(ID, 4.) = compress(vname(_year(i+2)),, 'kd') 
    then _flag(i)=1;

    else _flag(i)=0;
end;

drop i;

运行;

data referenceratecontract;
set referenceratecontract;
keep flag2017--flag2020;
run;

根据Id = Year + 2i,TIA

寻找标记方式
***else if put(ID, 4.) = compress(vname(_year(i+2)),, 'kd') then _flag(i)=1;***

1 个答案:

答案 0 :(得分:0)

问题是我应该放I - 2而不是I + 2

另外,我必须更改数组限制,因为我的hbound试图迭代到矩阵的末尾。
