getScaleCoef: Extract scaling coefficients from vector returned by...
In qra: Quantal Response Analysis for Dose-Mortality Data
Description
Usage
Arguments
Details
Value
Examples
Description
The function scale() replaces x by (x-a)/b,
where a is mean(x) and b is sd(x).
The quantities a and b are available as attributes
of the object that is returned.
Usage
1
getScaleCoef(z)
Arguments
z
Object returned by scale()
Details
Use of a scaled explanatory variable can be helpful in getting a
model to fit. The scaling coefficient(s) will then be needed when
the fitted model is used with explanatory variable values on the
original scale.
Value
A vector, whose elements are the scaling coefficients
a and b, or if scale=FALSE then a.
Examples
1
2
z <- scale(1:10)
qra::getScaleCoef(z)
