# 繪製 Empirical Cumulative Density Plot (ECDF) """ YOUR CODE HERE """  data = app_train['AMT_INCOME_TOTAL'] num_bins = 50  # Use the histogram function to bin the data counts, bin_edges = np.histogram(data, bins=num_bins, normed=True)  # Now find the cdf cdf = np.cumsum(counts)  #plot plt.plot(list(cdf.index), cdf/cdf.max())

如上之取得cdf的方式是否有誤，因在要畫圖時，顯示"'numpy.ndarray' object has no attribute 'index'"，應該是變數格式有錯誤？再麻煩解答，感恩！
