Model Form:

Model Form #1

log₁₀(SSR) = 0.312 + 0.97 log₁₀(TURB)

where:

SSR is computed suspended sediment, in milligrams per liter
TURB is turbidity, YSI model 6136, in formazin nephelometric units

Model Calibration

Basic Data

Number of measurements:	35
Mean squared error:	0.009025
Multiple R²:	0.958
Bias correction (smearing) factor:	1.02717

Explanatory Variables

Variable	Value	Standard error
Intercept	0.312	0.095
log₁₀(TURB)	0.97	0.0346

Correlation Matrix

A correlation matrix is not available for this model. Therefore, the prediction interval was calculated by assuming that there is no correlation between the explanatory variables.
