<p>Statistical modeling involves collecting data and building a data-driven model to describe the relationship between variables or make predictions, while theoretical modeling is based on theoretical assumptions and does not necessarily require data collection.</p> Signup and view all the answers

<p>Residuals can be used to compare the predicted values from the model with the actual observed values, helping to assess the accuracy and effectiveness of the model.</p> Signup and view all the answers

<p>Statistical modelling involves collecting data, producing graphs, and building a data-driven model, like a least squares equation or a least squares model. It is used to describe the relationship between variables or make predictions. Theoretical modelling, on the other hand, involves thinking about how the scientific system works and putting that into a model.</p> Signup and view all the answers

<p>The correlation between the incidence of MVE outbreaks and the SOI was found to be greater than or equal to 5 on 100% of occasions when there was an MVE outbreak.</p> Signup and view all the answers

<p>Sugar cane production was studied using a statistical model to evaluate the correlation between climate signals and cane yields. The SOI phase for October to November was used for climate data, while cane yield data was collected. A quadratic model was used to fit the data, as it was a non-stationary series with a changing mean over time.</p> Signup and view all the answers
