如何解决选择多行的问题
我有这种格式的数据 - 这只是一个
例子: n=2
X Y info
2 1 good
2 4 bad
3 2 good
4 1 bad
4 4 good
6 2 good
6 3 good
现在,以上数据已排序(总共 7 行)。我需要分别制作一组 2 、 3 或 4 行并生成一个图表。在上面的数据中,我制作了一组 2 行。第三行被单独保留,因为第三行中没有其他列可以形成一个组。一个组只能在同一行内形成。不与其他行。
现在,我将检查这两行的信息列中是否都有“good”。如果两行都有“好”,则形成的组也好,否则不好。在上面的例子中,第三组/最后一组是“好”组。剩下的都是坏组。完成所有行后,我将计算总数。形成的良好团体数量/总数组。
在上面的示例中,输出将为:Total no。优秀团体数/总数组数 => 1/3。
这是 n=2(组大小)的情况
现在,对于 n=3,我们制作 3 行的组,对于 n=4,我们制作 4 行的组,并以类似的方式找到好/坏的组。如果组中的所有行都有“好”块,则结果是好块,否则结果是坏块。
示例:n= 3
2 1 good
2 4 bad
2 6 good
3 2 good
4 1 good
4 4 good
4 6 good
6 2 good
6 3 good
在上面的情况下,我保留了第 4 行和最后 2 行,因为我无法用它们组成 3 行组。第一组结果是“坏”,最后一组结果是“好”。
输出:1/ 2
对于 n= 4:
2 1 good
2 4 good
2 6 good
2 7 good
3 2 good
4 1 good
4 4 good
4 6 good
6 2 good
6 3 good
6 4 good
6 5 good
在这种情况下,我将 4 人分成一组并求出结果。第 5、6、7、8 行被留下或忽略。我制作了 2 组,每组 4 行,都是“好”块。 输出:2/2
因此,在获得 n=2 、 n-3 和 n=4 的 3 个输出值之后,我将绘制这些值的图表。
I have the data in this format- it is just an
example: n=2
X Y info
2 1 good
2 4 bad
3 2 good
4 1 bad
4 4 good
6 2 good
6 3 good
Now, the above data is in sorted manner (total 7 rows). I need to make a group of 2 , 3 or 4 rows separately and generate a graph. In the above data, I made a group of 2 rows. The third row is left alone as there is no other column in 3rd row to form a group. A group can be formed only within the same row. NOT with other rows.
Now, I will check if both the rows have “good” in the info column or not. If both rows have “good” – the group formed is also good , otherwise bad. In the above example, 3rd /last group is “good” group. Rest are all bad group. Once I’m done with all the rows, I will calculate the total no. of Good groups formed/Total no. of groups.
In the above example, the output will be: Total no. of good groups/Total no. of groups => 1/3.
This is the case of n=2(size of group)
Now, for n=3, we make group of 3 rows and for n=4, we make a group of 4 rows and find the good /bad groups in a similar way. If all the rows in a group has “good” block—the result is good block, otherwise bad.
Example: n= 3
2 1 good
2 4 bad
2 6 good
3 2 good
4 1 good
4 4 good
4 6 good
6 2 good
6 3 good
In the above case, I left the 4th row and last 2 rows as I can’t make group of 3 rows with them. The first group result is “bad” and last group result is “good”.
Output: 1/ 2
For n= 4:
2 1 good
2 4 good
2 6 good
2 7 good
3 2 good
4 1 good
4 4 good
4 6 good
6 2 good
6 3 good
6 4 good
6 5 good
In this case, I make a group of 4 and finds the result. The 5th,6th,7th,8th row are left behind or ignored. I made 2 groups of 4 rows and both are “good” blocks.
Output: 2/2
So, After getting 3 output values for n=2 , n-3, and n=4 I will plot a graph of these values.

下面是我认为得到您正在寻找的内容的代码。它假设您描述的数据分别存储在名为 data_2、data_3 和 data_4 的三个数据集中。每个数据集都由 %FIND_GOOD_GROUPS 宏处理,该宏确定哪些 X 组在 INFO 中具有所有“GOOD”值,然后将此摘要信息作为新行附加到 BASE 数据集。我没有添加代码,但您可以在单独的数据步骤中计算 GOOD_COUNT 与 FREQ 的比率,然后使用过程来绘制 N 值和比率。希望这接近您想要实现的目标。
Below is code that I think is getting what you are looking for. It assumes that the data that you described is stored separately in the three datasets named data_2, data_3, and data_4. Each of these datasets is processed by the %FIND_GOOD_GROUPS macro that determines which groups of X have all "GOOD" values in INFO, then this summary information is appended as a new row to the BASE dataset. I didn't add the code, but you could calculate the ratio of GOOD_COUNT to FREQ in a separate data step, then use a procedure to plot the N value and the ratio. Hope this gets close to what you're trying to accomplish.
