Box-Cox {rmutil} | R Documentation |
These functions provide information about the Box-Cox
distribution with location parameter equal to m
, dispersion
equal to s
, and power transformation equal to f
: density,
cumulative distribution, quantiles, log hazard, and random generation.
The Box-Cox distribution has density
f(y) = 1/sqrt(2 pi s^2) exp(-((y^f/f - mu)^2/(2 s^2)))/ (1-I(f<0)-sign(f)*pnorm(0,m,sqrt(s)))
where m is the location parameter of the distribution, s is the dispersion, f is the family parameter, I() is the indicator function, and y>0.
f=1 gives a truncated normal distribution.
