Produces a Q-Q plot of the data against a specified von Mises distribution to graphically assess the goodness of fit of the model.
Usage
vm_qqplot(
x,
w = NULL,
axial = TRUE,
mean = NULL,
kappa = NULL,
xlab = "von Mises quantile function",
ylab = "Empirical quantile function",
main = "von Mises Q-Q Plot",
...
)
Arguments
