Description Usage Arguments Details Value Examples
This function determines whether a non-linear spline model of the dose-response relationship differs significantly from a linear model across all doses.

Name of dose column in dataframe. |

Name of response column in dataframe. |
data |
Input dataframe. |
The non-linear spline model (output "Model 2") is compared to the linear model (output "Model 1") using an anova F-test. If the spline model fits the data signficantly better, the F will be large and the associated p value will be significant.
The nlaad, nlbcd, and lbcd functions are currently only intended for use on continuous outcome data.
The analysis of variance table comparing the non-linear spline model with the linear model to assess non-linearity across all doses.
