私はPythonと線形回帰を学んでいます。私は初心者なので、問題は解決できません。KeyError： 'DystopiaResidual'、パンダのエラー
マイコード：
import numpy as np # linear algebra
import pandas as pd # data processing, CSV file I/O (e.g. pd.read_csv)
from sklearn.utils import shuffle
from sklearn.metrics import confusion_matrix
import seaborn as sns
import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec
from sklearn.preprocessing import StandardScaler
from sklearn.manifold import TSNE
from subprocess import check_output
print(check_output(["ls", "input"]).decode("utf8"))
df1 = pd.read_csv("input/2015.csv")
df2 = pd.read_csv("input/2016.csv")
df1.columns
df1.head(2)
sns.regplot(x='Standard Error',y='Happiness Score' ,data=df1)
sns.regplot(x='Economy (GDP per Capita)',y='Happiness Score' ,data=df1)
fr=['Standard Error', 'Economy (GDP per Capita)', 'Family','Health (Life Expectancy)', 'Freedom', 'Trust (Government Corruption)','Generosity', 'DystopiaResidual']
plt.figure(figsize=(12,28*4))
gs = gridspec.GridSpec(28, 1)
for i, cn in enumerate(fr):
ax = plt.subplot(gs[i])
#sns.distplot(df1[cn], bins=50)
sns.regplot(x=df1[cn],y='Happiness Score' ,data=df1)
ax.set_xlabel('')
ax.set_title('Regrassion of feature: ' + str(cn))
plt.show()
エラー：私は問題が何であるかを理解していない
