Question

from statsmodels.tsa.stattools import adfuller
def test_stationarity(timeseries):

    #Determing rolling statistics
    rolmean = pd.rolling_mean(timeseries, window=24) # 24 hours on each day
    rolstd = pd.rolling_std(timeseries, window=24)

    #Plot rolling statistics:
    orig = plt.plot(timeseries, color='blue',label='Original')
    mean = plt.plot(rolmean, color='red', label='Rolling Mean')
    std = plt.plot(rolstd, color='black', label = 'Rolling Std')
    plt.legend(loc='best')
    plt.title('Rolling Mean & Standard Deviation')
    plt.show(block=False)

    #Perform Dickey-Fuller test:
    print ('Results of Dickey-Fuller Test:')
    dftest = adfuller(timeseries, autolag='AIC')
    dfoutput = pd.Series(dftest[0:4], index=['Test Statistic','p-value','#Lags Used','Number of Observations Used'])
    for key,value in dftest[4].items():
        dfoutput['Critical Value (%s)'%key] = value
    print (dfoutput)

from matplotlib.pylab import rcParams
rcParams['figure.figsize'] = 20,10

test_stationarity(train_original['Count'])

Answer 1

我将假定标题错误应为AttributeError: module 'pandas' has no attribute 'rolling_mean'，因为我认为它已被弃用然后再删除。另外，pd.rolling不在提供的代码中。在这种情况下，您应该使用rolling。假设timeseries是pd.Series：

from statsmodels.tsa.stattools import adfuller
def test_stationarity(timeseries):

    #Determing rolling statistics
    rolmean = timeseries.rolling(window=24).mean() # 24 hours on each day
    rolstd = timeseries.rolling(window=24).std()

Answer 2

尝试执行 conda install -c conda-forge statsmodels，根据之前的语法，笔记本无法识别 adfuller。然后尝试 pip uninstall pandas 并执行 pip install pandas。对于类似情况，可以尝试链接 Numpy is installed but still getting error

Answer 3

from statsmodels.tsa.stattools import adfuller
def test_stationarity(timeseries):
    #determine rolling statistics
    rolmean = pd.Series(timeseries).rolling(window=24).mean()#24 hours on each day
    rolstd = pd.Series(timeseries).rolling(window=24).std()
    #plot rolling statistics
    orig = plt.plot(timeseries,color = 'blue',label='original')
    mean = plt.plot(rolmean,color = 'red',label = 'rolling mean')
    std = plt.plot(rolstd,color = 'black',label = 'rolling std')
    plt.legend(loc = 'best')
    plt.title('rolling mean and standard deviation')
    plt.show(block = False)
    #perform dickey fuller test
    print('result of dickey fuller test:')
    dftest = adfuller(timeseries,autolag = 'AIC')
    dfoutput = pd.Series(dftest[0:4],index = ['Test statistics', 'p-value', '#lags used', 'number of observation used'])
    for key,value in dftest[4].items():
        dfoutput['critical value (%s)'%key] = value
    print(dfoutput)

from matplotlib.pylab import rcParams
rcParams['figure.figsize'] = 20,10
test_stationarity(train_original['Count'])

AttributeError：模块“ pandas”没有属性“ rolling”
