Dalam analisis deret waktu, rata-rata pergerakan<\/strong> hanyalah nilai rata-rata dari sejumlah periode sebelumnya.<\/span><\/p>\n

Rata-rata pergerakan eksponensial<\/strong> adalah jenis rata-rata bergerak yang lebih menekankan pengamatan terkini, yang berarti mampu menangkap tren terkini dengan lebih cepat.<\/span><\/p>\n

Tutorial ini menjelaskan cara menghitung rata-rata pergerakan eksponensial untuk kolom nilai di pandas DataFrame.<\/span><\/p>\n

Contoh: rata-rata pergerakan eksponensial pada panda<\/strong><\/h3>\n

Misalkan kita memiliki panda DataFrame berikut:<\/span><\/p>\n

 import<\/span> pandas as<\/span> pd\n\n#createDataFrame<\/span>\ndf = pd.DataFrame({'period': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],\n                   'sales': [25, 20, 14, 16, 27, 20, 12, 15, 14, 19]})\n\n#view DataFrame<\/span> \ndf\n\n        period sales\n0 1 25\n1 2 20\n2 3 14\n3 4 16\n4 5 27\n5 6 20\n6 7 12\n7 8 15\n8 9 14\n9 10 19\n<\/strong><\/pre>\n
 Kita dapat menggunakan fungsi pandas.DataFrame.ewm()<\/a> untuk menghitung rata-rata pergerakan tertimbang secara eksponensial untuk beberapa periode sebelumnya.<\/span><\/p>\n
 Misalnya, berikut cara menghitung rata-rata pergerakan tertimbang secara eksponensial menggunakan empat periode sebelumnya:<\/span><\/p>\n
 #create new column to hold 4-day exponentially weighted moving average<\/span>\ndf['4dayEWM'] = df['sales']. ewm<\/span> (span= 4<\/span> , adjust= False<\/span> ). mean<\/span> ()\n\n#view DataFrame<\/span> \ndf\n\n        period sales 4dayEWM\n0 1 25 25.000000\n1 2 20 23.000000\n2 3 14 19.400000\n3 4 16 18.040000\n4 5 27 21.624000\n5 6 20 20.974400\n6 7 12 17.384640\n7 8 15 16.430784\n8 9 14 15.458470\n9 10 19 16.875082<\/strong><\/pre>\n
 Kita juga dapat menggunakan pustaka matplotlib untuk memvisualisasikan penjualan relatif terhadap rata-rata pergerakan tertimbang secara eksponensial 4 hari:<\/span> <\/p>\n
 import<\/span> matplotlib.pyplot as<\/span> plt\n\n#plot sales and 4-day exponentially weighted moving average<\/span>\nplt. plot<\/span> (df['sales'], label='Sales')\nplt. plot<\/span> (df['4dayEWM'], label='4-day EWM')\n\n#add legend to plot<\/span>\nplt. legend<\/span> (loc=2)\n<\/strong><\/pre>\n
