The Model in Full
THIS SECTION PRESENTS EVERYTHING WE FOUND IN OUR STUDY that has a predictive effect on salary—with the warning, as stated earlier, that the variables may not control or cause salary changes. The model has an R-squared of 0.475, which means that the model explains approximately 48% of the variation in the sample salaries.
To use the model, proceed through the coefficients and add or subtract the ones associated with a feature that applies to you. Remember that some coefficients are multiplied by a factor: number of hours in your work week, years of experience, numbers of tools in a cluster. Once you sum up the coefficients, you will obtain an estimate for your annual total salary in US dollars.
