Which equation best represents the line of best fit for the scatter plot? The equation that best represents the line of best fit for the scatter plot is a straight line, usually represented by the equation y = mx + b. m being the slope and b being the y intercept.What...

When data is visualized on a scatterplot, we often are interested in the line of best fit or the regression line. Linear equations occur frequently in all mathematics and their applications in physics and engineering, partly because non-linear systems are often well approximated by linear ...
RMSE indicates the spread around the line of best fit. RMSE = ∑i=1n(Pi−Oi)2/n Where Pi is the predicted value for the ith observation, Oi is the observed value for ith observation and n is the sample size. MPE = tα× (SEE / y¯) / n× 100 Where tα is the t value...
The CHIME equation had the best discrimination for renal failure (AUROCs from CHIME, UKPDS-OM2 and RECODe: 0.77, 0.60 and 0.64, respectively). All three equations overestimated renal failure risk (calibration slope < 1). After rigorous updating, the calibration slope/intercept of the re...
Best fit equations (or SWCC equations) are commonly used for the representation of the SWCC. As the infiltration into the unsaturated soil is mainly governed by the hydraulic properties of soil, the SWCC equations play important roles in the assessment of the rainwater infiltration. In this paper...
For the model among participants without diabetes, for which albuminuria values were available only in a minority of individuals, a patch approach was used.12 Models were fit in all the cohorts using all variables except albuminuria, and data were combined as described above. The weighted-average...
