TOOLS > STATISTICS > VECTOR > ANOVA

PURPOSE Performs an ANOVA with a significance based upon a permutation test.

DESCRIPTION Undertakes a standard analysis of variance but uses a permutation test to generate the significance level so that standard assumptions on independence and random sampling are not required.   

PARAMETERS 
   
Dependent (Y) variable:
Name of file containing the dependent vector, this must be a UCINET data file. Enter the filename followed by ROW (or COL) and a number to specify which row or column of the file to use.

Independent (X) variable:
Name of file containing the independent vector, this must  UCINET data file. Enter the filename followed by ROW (or COL) and a number to specify which row or column of the file to use.

Number of random permutations: (Default = 5000)
The larger the number of permutations, the better the estimates of standard error and "significance", but the longer the computation time.

Random number seed:
The random number seed sets off the random permutations. UCINET generates a different random number as default each time it is run.  This number should be changed if the user wishes to repeat an analysis.  The range is 1 to 32000.

  
LOG FILE
A standard analysis of variance table together with the significance value derived from the permutation test.
