JSL - 如何迭代双变量并将所有样条线保存到 1 列你好。我创建了一个字符串数组，其中包含在我的一列中找到的各种值。 我想为字符串数组中的每个值生成一个样条曲线，并将所有预测点保存到新列中。我能够迭代 Bivariate()，将每次迭代的 where 子句更改为字符串数组中的新值，但是，只有最后的预测点会保存到新列中。如何将所有预测点保存到新列中？谢谢。
Proc = "new";
processArray = {};
DataCV=open("C:\Desktop\JMP\sample_data.csv");
for (l = 1, l < 32521, l++, // Generate array of strings
if (proc == (Row()=l; :process),
print("same process"),
Insert Into(processArray, (Row()=l; :process)); proc = (Row()=l; :process); Show(proc)
);
);
for (n = 1, n <= length(processArray), n++, // Generate and save multiple predicteds
biv = Bivariate(
Y( :c_mm_deembed_pf ),
X( :v_dut_volt ),
Where( :c_type == "Cdg" & :process == processArray[n] ),// :process == processArray[n] appears to be working, as 6 splines are generated
Fit Spline( 0.1, standardized, {save predicteds}) // {save predicteds} is not saving all 6 splines, only last spline
);
); 
回复：JSL - 如何迭代双变量并将所有样条线保存到 1 列尝试使用 By() 角色来获取同一列中的所有预测。 这样就不需要对列表进行迭代，生成的预测公式将自动应用条件语句来分隔副列的不同值。 主要区别在于所有绘图将共享同一个窗口。
DataCV = Open("C:\Desktop\JMP\sample_data.csv");
DataCV << biv = Bivariate(
Y(:c_mm_deembed_pf),
X(:v_dut_volt),
By(:process),
Where(:c_type == "Cdg"),
Fit Spline(0.1, Standardized, {Save Predicteds})

哎呀。 我没有看到后来的帖子，而是使用 Eval Expr 而不是 Substitute 回答了之前的问题。
我无意重复回复。
抱歉，吉姆。
回复：JSL - 如何迭代双变量并将所有样条线保存到 1 列而且，我只是再次考虑了“预测”列的“预测”公式，并意识到您正在使用的过程将在处理时相互写入。我建议您在每次执行二元变量后重命名 Prediced 列，强制每次迭代最终创建一个新列。
回复：JSL - 如何迭代双变量并将所有样条线保存到 1 列这是脚本的带注释的修改版本。试试看。我相信它会与您的数据配合使用。我无法真正做好测试，但任何错误都应该很小
