can {fpc} | R Documentation |
Generates tuning constants ca
for fixreg
dependent on
the number of points and variables of the dataset.
Only thought for use in fixreg
.
can(n, p)
n |
positive integer. Number of points. |
p |
positive integer. Number of independent variables. |
The formula is 3+33/(n*2^{-(p-1)/2})^{1/3}+2900000/(n*2^{-(p-1)/2})^3. For justification cf. Hennig (2002).
A number.
