所以我有两个变量平均值和服务值,由以下值组成:
mean=[5.76,6.5,7,5,4.5,6,9,2.5,3,5.5]
limit=[90,80,95,96,98,85,82,75,90,91]
现在,我对变量平均值应用了
poisson
函数:from scipy.stats import poisson
for m in mean:
r_v=poisson(m)
r_v1.append(r_v)
接下来我需要做的是得到所有平均值的pmfs之和(出现次数从0开始),并将它们与limit中的相应值进行比较。我需要得到pmfs之和大于或等于相应极限值的发生次数。例如,平均值=5.76,(pmf(0)+pmf(1)…+pmf(9))*100=93.2,这在9次发生的极限变量中超过90。
我运行了以下代码,看起来运行良好:
for r,s in zip(r_v1, limit):
l=[]
z=0
while True:
y=r.pmf(z)
l.append(y)
z+=1
if round(sum(l),2)*100>=s:
break
Store=%z
问题是,当我试图存储最后一个出现在
round(sum(l),2)*100>=s
处的z时,会出现以下错误:ERROR:root:Line magic function `%z` not found.
有人能帮我纠正代码中的错误吗?谢谢。
最佳答案
%
是调用IPython的交互式shell中的magic line函数的前缀,并且没有z
line magic函数,因此会出现此错误。
在IPython中键入%quickref
,您将获得可用魔术功能的概述或readthedocs。
你的问题是你一步做得太多了。尝试为一个输入获取正确的结果,然后在另一个步骤中累积:
def calc(mean_, limit_):
def inner(m, s):
r = poisson(m)
l = []
z = 0
while True:
y = r.pmf(z)
l.append(y)
z += 1
if round(sum(l), 2) * 100 >= s:
return z, l
return [inner(*args) for args in zip(mean_, limit_)]
呼叫
calc(mean, limit)
