  • The width of the 80% prediction interval for this forecast in March of 2027 is 60 dollars.
  • These three residual plots allow the analyst to examine the distribution of the residuals of the modeled time series.

  • Despite increasing volatility, our stock price model is estimated to be 93.5% accurate.

  • This doesn’t guarantee that forecasts will be 93.5% accurate but it does improve our chances of accurate forecasting.
