Question

我在下面的代码“simulation_tracking3”之前有一个数据步骤，输出如下内容：

CDFx Allowed_Claims
.06   120
.12   13
.15   1400

我希望我的哈希表根据随机生成的值（从0到1）对Allowed_Claims求平均值。例如，让我们称之为进程A ，如果Px = rand（'Uniform'，0,1）得到.09，我希望它在Allowed_Claims值之间取平均值，其中Px = .06和Px = 0.12，即（120 + 13）/ 2

数组的作用是它决定了我想要的进程A的迭代次数。数组是

Members {24} _temporary_ (5 6 8 10 12 15 20 25 30 40 50 60 70 80 
                                    90 100 125 150 175 200 250 300 400 500);

因此，当循环开始时，它将执行过程A的5次迭代，从而产生5个平均的“allowed_claims”值。我想要这五个主张的总和。

然后，循环将继续并执行过程A的6次迭代并产生6个平均的“allowed_claims”值。同样，我想要这6个主张的总和。

我希望输出表看起来像：

`

Member[i]    Average_Expected_Claims
   5              (sum of 5 'averaged 'claims) 
   6              (sum of 6 'averaged' claims) 
   8              (sum of 8 'averaged' claims)

我目前拥有的代码如下。我的错误发生在这里：

do rc = hi_iter.first() by 0 until (hi_iter.next()_ ne 0 or CDFx gt rand_value);

rc = hi_iter.prev();
