Description |
Vector Rose is an orientation analysis application that calculates circular-normal statistics and plots a circular histogram, linear histogram or class frequencies for any set of angular data, or any data with a circular normal distribution. Statistics include: number of observations; maximum class frequency; maximum class frequency by %; class mode; azimuth of resultant vector; standard angular deviation; mean resultant length or polar coordinate; distance from origin; vector magnitude or length of the resultant vector; consistancy ratio or % of normalized magnitude of resultant vector; Rayleigh test; F-test; Watson's two-sample nonparametric test. The program features unidirectional or bidirectional circular (rose or flight-bearing) histograms, with the diagrams scaled relative to maximum class frequency (length or equal area), or scaled relative to 100%. Class interval limits are provided for all divisions evenly divisable into 360, from 1 to 180 degrees. The axis scale may be represented as concentric circles or as a vertical line with tick marks. The position of North or 0 degrees can be rotated to any desired position. Data can be entered by reading text files (Excel, Word, SimpleTEXT, etc.). All data is error checked. |
