Comparison of actual reading data Y compared to predictions by applying the Fourier theoretical model.

Mean-square error and mean absolute error are presented for all readings as well as for a test set containing a random 20% sample of the data. The mean and standard deviation of the difference in predictions are also attached (). The differences between predictions are shown in Celsius degrees.本数据集给出了全部读数以及随机抽取20%数据构成的测试集的均方误差（Mean-square error）与平均绝对误差（Mean absolute error）。同时还附上了预测差值的均值与标准差（）。预测差值的单位为摄氏度。
