Netlogo 如何计算标题的加权平均值？

从这个答案中我得到了部分答案，但我希望每个标题都要根据海龟的大小来加权

差不多

 sum [heading * size] of turtles / sum [size] of turtles

---

但那会，你知道，真正起作用

如果您接受套头衫而不是标题列表，则：

to-report weighted-mean-heading [turts]
  let mean-x mean [size * sin heading] of turts
  let mean-y mean [size * cos heading] of turts
  report atan mean-x mean-y
end

看起来不错，不过我得先测试一下。谢谢。你刚刚回答了这个问题

to-report weighted-mean-heading [turts]
  let mean-x mean [size * sin heading] of turts
  let mean-y mean [size * cos heading] of turts
  report atan mean-x mean-y
end
