What function is used to model the burnout variable, and what does the notation "𝛽1×Loan Age+𝛽2×Incentive" represent in this function?
The burnout function is exponential and takes the form "burnout = exp(𝛽1×Loan Age+𝛽2×Incentive)". "𝛽1×Loan Age+𝛽2×Incentive" represents a linear combination of the loan age and incentive, where 𝛽1 and 𝛽2 are coefficients.
