derivationTable {cNORM} | R Documentation |
Create a table based on first order derivative of the regression model for specific age
Description
In order to check model assumptions, a table of the first order derivative of the model coefficients is created.
Usage
derivationTable(
A,
model,
minNorm = NULL,
maxNorm = NULL,
step = 0.1,
covariate = NULL
)
Arguments
A |
the age |
model |
The regression model or a cnorm object |
minNorm |
The lower bound of the norm value range |
maxNorm |
The upper bound of the norm value range |
step |
Stepping parameter with lower values indicating higher precision |
covariate |
In case, a covariate has been used, please specify the degree of the covariate / the specific value here. |
Value
data.frame with norm scores and the predicted scores based on the derived regression function

Examples
# Generate cnorm object from example data
cnorm.elfe <- cnorm(raw = elfe$raw, group = elfe$group)
# retrieve function for time point 6
d <- derivationTable(6, cnorm.elfe, step = 0.5)
