python - 将预言家预测反馈到数据集 - Python

Question

假设我训练了 Prophet 的模式：

weekly.columns = ['y', 'ds']# change column names so that Prophet likes them
m = Prophet(growth = "linear", mcmc_samples = 0,
            holidays=holidays, holidays_prior_scale=1,
            seasonality_mode = "multiplicative",
            seasonality_prior_scale = 10,
            changepoint_prior_scale=1, 
            #n_changepoints = 5,
            yearly_seasonality=False, 
            weekly_seasonality=False, 
            daily_seasonality=False, interval_width =0.95).fit(weekly)
future = m.make_future_dataframe(periods=1, freq='W')
fcst = m.predict(future)

然后，使用了下周的预测。因此，预测包含大量不同属性的列表。将预测与实际数据一起获得更好的方法是什么？

#making a forecast
future = m.make_future_dataframe(periods = 1, freq = 'w')
forecast = m.predict(future)
forecast[['ds', 'yhat', 'yhat_lower', 'yhat_upper']].tail()

forecast['actuals'] = weekly['y']?
