HyperbPlots {HyperbolicDist} | R Documentation |
qqhyperb
produces a hyperbolic Q-Q plot of the values in
y
.
pphyperb
produces a hyperbolic P-P (percent-percent) or
probability plot of the values in y
.
Graphical parameters may be given as arguments to qqhyperb
,
and pphyperb
.
qqhyperb(y, Theta, main = "Hyperbolic Q-Q Plot", xlab = "Theoretical Quantiles", ylab = "Sample Quantiles", plot.it = TRUE, line = TRUE, ...) pphyperb(y, Theta, main = "Hyperbolic P-P Plot", xlab = "Uniform Quantiles", ylab = "Probability-integral-transformed Data", plot.it = TRUE, line = TRUE, ...)
