Nearest Neighbour Analysis Options

Selects information to be printed by the Nearest Neighbour Analysis menu.


This specifies which items of output are to be produced by the analysis.

Model Details of the model that is fitted
Wald tests Wald tests of the fixed effects
Variance components Estimated variance components
Treatment means Estimated treatment means
Treatment effects Estimated treatment effects (note these are centred to sum to zero)
Standard errors of differences between treatment effects Symmetric matrix of standard errors of differences between treatment effects
Residual checks Uses the VCHECK procedure to check the residuals for outliers and variance stability

Calculate treatment SEDs using

Specifies the method used in estimating the standard errors of differences.

REML Use the residual maximum likelihood estimators of the SEDs
Simulation Use simulation where random terms with the estimated variance components are simulated to estimate the SEDs

Number of simulations

This defines the number of simulations to use when calculating the SEDs by simulation, and must be a positive integer. Using a large value takes longer, but gives a more precise estimate of the SEDs (assuming that the data do follow the nearest neighbour model).


This defines the seed to initialize the random number generation used for calculating the SEDs by simulation. A zero value initializes this from the computer clock, or a nonzero value gives repeatable results.
