Box-Cox transform
Compute the box-cox transform of a vector of values, handling the region near lambda = 0 with some care
bc(y, lambda, eps = 1e-04)
y |
numeric, the original observations |
lambda |
numeric, the box-cox power |
eps |
numeric, a guard aroung lambda = 0 |
A vector of transformed quantities
plot(12:50, bc(12:50, -1), type = "l", xlab = "MPG", ylab = "bc(MPG, -1)",
las = 1, col = "sky blue", panel.first = grid())
points(bc(MPG.city, -1) ~ MPG.city, data = Cars93, pch = 16, cex = 0.7)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
