This changes the behavior slightly from previous relaeses, in that input is not reshaped anymore into vector format.

As a last argument, add the dimension along which you want to average. Since 2010, most functions for descriptive statistics can be used in Matlab style matrix computations. For a detailed description of arguments and outputs consult the help text in the files.

Returns the p-value and indicates whether the hypothesis of uniformity can be accepted.

One way to obtain a set of azimuths from X and Y coordinates of the vectors is to use the LoadData function. If the space deviates much from this value, then the probability that the data belong to a uniform distribution is reduced.

The default is 0.01.ДЇor a uniform distribution, the space between points should be approximately 360/n. Value used to obtain the Rao Value of the Rao Table. ZarвЂ™s Biostatistical Analysis, Fifth Edition, is the ideal textbook for graduate and undergraduate students seeking practical coverage of statistical analysis methods used by researchers to collect, summarize, analyze and draw conclusions from biological research.The latest edition of this best-selling textbook is both comprehensive and easy to read. Vector containing the values of the azimuths This function performs the Rao test of uniformity.
