est.rho {CircStats} | R Documentation |
Returns the mean resultant length of a vector of circular data.
est.rho(x)
x |
vector of data points measured in radians. |
Each observation is treated as a unit vector, or point on the unit circle. The resultant vector of the observations is found, and the length of the resultant vector divided by the sample size is returned.
Returns the mean resultant length of data.
