从NetLogo中的有界正态分布中选择值

我正在尝试让NetLogo根据stackoverflow中上一个问题中的建议从有界随机正态分布中绘制值

NetLogo : How to make sure a variable stays in a defined range?

具体而言,我要求模型根据经验数据创建一个大小不同的圆形家庭范围

set homerange patches in-radius ((sqrt (( random-normal-in-bounds [ 54.4 35.8 19 151 ] * 1000000)/ pi))/ 100)

to-report random-normal-in-bounds [mid dev mmin mmax]
  let result random-normal mid dev
  if result < mmin or result > mmax
    [ report random-normal-in-bounds mid dev mmin mmax ]
  report result
end

但是我不断得到随机正常入境预期4个输入的错误。我确定这是我在做的傻事,但它看起来像4输入(54.4,35.8,19,151)给我。关于我做错的任何建议?提前谢谢!

答案 0 :(得分:1)

我认为您的错误是由[]引起的,您不需要这些括号。

to test
clear-all
let homerange  nobody
let radius sqrt (( random-normal-in-bounds  54.4 35.8 19 151  * 1000000)/ pi) / 100 
crt 1 [
set homerange  patches in-radius radius
]
ask homerange  [set pcolor violet]
end
to-report random-normal-in-bounds [mid dev mmin mmax]
  let result random-normal mid dev
  if result < mmin or result > mmax
    [ report random-normal-in-bounds mid dev mmin mmax ]
  report result
end
