Density Estimation for Circular Data
Computes a kernel smoothed estimate of the probability density for angular data.
- Keywords
- smooth, nonparametric
Usage
circdensity(x, sigma = "nrd0", …,
bw = NULL,
weights=NULL, unit = c("degree", "radian"))
Arguments
- x
Numeric vector, containing angular data.
- sigma
Smoothing bandwidth, or bandwidth selection rule, passed to
density.default
.- bw
Alternative to
sigma
for consistency with other functions.- …
Additional arguments passed to
density.default
, such askernel
andweights
.- weights
Optional numeric vector of weights for the data in
x
.- unit
The unit of angle in which
x
is expressed.
Details
The angular values x
are smoothed using
(by default) the wrapped Gaussian kernel with standard deviation sigma
.
Value
An object of class "density"
(produced by
density.default
) which can be plotted
by plot
or by rose
.
