Sentence examples for using the cubic regression from inspiring English sources
Nine-point methylation curves were used to calibrate the samples run in different plates and to correct for PCR bias using the cubic regression method described previously (46).
We reduced the number of degrees of freedom used in the cubic regression spline for time to reflect the percentage of total days available for the model.
The use of the cubic regression-based correction benefits the accuracy and the power of discrimination in methylation studies.
Moreover, we show that b values depart much more from 1 when calculated with uncorrected observed methylation values compared with corrected estimations, so that systematic use of the cubic regression-based correction enormously benefits both the accuracy and the power of discrimination in methylation studies.
When entering independent variables, the cubic regression equation could be used to estimate an administered dosage with an accuracy of ±10%% for 62%% of all patients and ±20%% for 90%% of all patients.

A generalized additive model (GAM) (Hastie and Tibshirani 1990) was fitted using a cubic regression spline for the ΣPCBs to further examine the shape of the dose response curve.
GAMs was performed using a cubic regression spline for the exposure with one knot every 8°C [ 3].
Once the best exposure window was determined, we fit a penalized spline model using a cubic regression spline with 12 knots to estimate the shape of the concentration response relation, and chose the optimal degree of freedom by minimizing AIC and evaluated nonlinearity with a Wald test.
