Study Notes

Residual Plots and Regression

Residual plots for linear, quadratic, and exponential regressions provide insights into the appropriateness of each model.
The shape and pattern of the residual plots can indicate which type of regression is most suitable for the data.

ATM Surcharge Fee Data

The average ATM surcharge fee data is modeled using exponential regression.
'Corresponds to 2002' indicates the starting point of the exponential regression model, which represents the year 2002.

Trend of ATM Surcharge Fees

From 2002 to 2014, the trend of ATM surcharge fees can be inferred from the exponential regression model.
