USGS Scientific Investigations Report 2012–5004  - Dependence of Flow and Transport through the Williamson River Delta, Upper Klamath Lake, Oregon, on Wind, River Inflow, and Lake Elevation 

Table 3. Summary of the best regression models for dependent variables. 

[Regression models are only valid for positive values of the dependent variable. Abbreviations:R², coefficient of determination of the regression; N, number of points on which the regression is based; RMSE, square root of mean of squared residuals; m, meter; m³/s, cubic meter per second; m/s, meter per second]
