      This should not be shown.

    2. Summary of SARIMAX Print the summary which includes AIC

      Why all these other headings? This is still part of the above?

      Yup, that won't mean a thing to most readers (myself included) unless you explain it.

    4. Rigorous validation is paramount to establishing the model’s reliability and practical application. To ensure the model’s generalizability, we will employ a train-test split.

      Why is this just being mentioned after all of the ML stuff has happened?

    5. The AIC value is: 561.5301944999834

      Which tells us what?

    6. Start date of the data: 2015-01-31 00:00:00 End date of the data: 2022-12-31 00:00:00

    7. To facilitate c

      The above graphic is a figure. Treat it as such!

      Also, use dashed lines for one of the entries so that we can see that they are actually perfectly overlapping and not just take your word for it.

    8. Plot Diag

      reference the figure correctly and explain it in the text!

      Also, give it an actual meaningful caption.

    9. The Mean Squared Error of our forecasts is 1.41

      units? What do you conclude from this?

    10. Forecasting Future Values As we conclude our modeling process, we generate predictions for the next 7 data points: Model Information: The result variable contains our fitted model’s details. Forecasting Method: We use the .get_forecast() method on our model results. Prediction Generation: This method analyzes observed patterns in our data to project future values. Output: We obtain forecasts for the next 7 time points, representing predicted air quality levels. This step transforms our analytical work into actionable insights for air quality management.

      I don't understand what you are trying to say or do here. You have already done some of this above (I think) so I'd guess this is a summary, except that some of this I'm pretty sure I haven't seen?

    11. Interpreting the Forecast Plot

      unnecessary

    12. Our plot

      Reference the figure number! And stick a caption on it!

      Is this plot for portland? That isn't apparent anywhere that I can see either.

    13. Represents the actual, historical air quality measurements Provides a baseline for comparing our predictions Forecasted Values (Orange Line) Depicts the future air quality levels predicted by our SARIMAX Time Series Model Allows us to visualize potential trends and patterns in air quality Confidence Interval (Shaded Region) The shaded area around the forecast line represents the 95% Confidence Interval (CI) Indicates the range within which we can be 95% confident that the true future values will fall Wider intervals suggest greater uncertainty in the prediction

      This is a publication. Use complete sentences.

    14. we have landed on these specific recommendations.

      Ok, let me just say that at this point, after reading through all your above analysis, I have NO IDEA what your recommendations are going to be. Which probably tells me that you did a poor job of actually showcasing your proof for each of these recommendations.

      I haven't read what they are yet, but for every recommendation you make, I should be able to go back to a specific section or figure and see the exact reason for why you would make that prediction. If that is not the case, then you are either making unfounded recommendations, or you are not communicating what your analysis was for clearly enough.

    15. exasperated by the dry heat and lack of rainfall

      Is this the actual cause? You showed some seasonality, I'm not sure these causes were showcased.

    16. As climate change raises temperatures and water sources dry up, wildfire season will continue to get worse over time.

      Agreed, how would you interpret your data in that light? Can you see evidence of that? Is the effect more pronounced in cities near lots of national forest? Otherwise you are just conjecturing.

    17. Weather conditions Wind speed and direction Temperature fluctuations Humidity levels Atmospheric pressure Solar radiation intensity

      Significantly affected? I thought you only saw a few of these at best as being significant contributors.

    18. That leaves us with three criteria gasses and all particulate matter.

      But again, these are just part of the definition of AQI aren't they? So of course they have a large impact?

    19. Industrial manufacturing processes and agriculture are significant polluters of the environment. We should invest in the research of more environmentally friendly manufacturing methods, working with materials that require less combustion, or are recyclable.

      Agreed, but I'm not sure you could see from your research if this was what was playing a large role?

    20. Bibliography

      Look up how to properly cite websites according to APA rules

    21. Algorithm Dependence. This is the reliability of forecasts which are inherently tied to the chosen predictive algorithms. Different models may yield varying results, emphasizing the importance of algorithm selection and validation.

      So how did you choose your algorithms with this in mind?

    22. The largest source of carbon monoxide, nitrogen dioxide, and ozone is the cars, trucks, and other vehicles we use daily (Environmental Protection Agency). We can lower our reliance on personal vehicles by utilizing public transportation, carpooling, walking, biking, increasing work from home to lower commutes when available, and overall be more considerate about if driving a car is necessary.

      Did you see evidence of this? You had bus data. Did cities with less traffic show decreases in these values?

    23. The impact of the geological features can be seen in the image below

      In what way?? EXPLAIN
