MATLAB: ANOVA Cofficients: anovan stats.coeffs

anovaanova coefficientsanovanStatistics and Machine Learning Toolboxstats structure

I want to understand coefficients in the stats struct returned by anovan. Are these coefficients the result of a linear regression model? How are they computed? How can I use these coefficients to compute the values predicted by the model. Guess stats.resid gives the difference between the actual and predicted values.

It is recommended to use fitglm instead of the older glmfit. Depending on the release of MATLAB (> R2012a) you can use either of the two:

You can access AIC, BIC etc as follows:

load hospital
modelspec = 'Smoker ~ Age*Weight*Sex - Age:Weight:Sex';
mdl = fitglm(hospital,modelspec,'Distribution','binomial')
mdl.ModelCriterion
ans = 
     AIC: 137.141380948166
    AICc: 138.358772252513
     BIC: 155.377572250082
    CAIC: 162.377572250082

MATLAB: Anovan: how to switch off the tables it produces

it's sufficient to write:

'display','off'

e.g.

    [p] = anovan(Meanfiring,{orientation,contrast,window},...
        'model',[1 0 0;0 1 0;0 0 1;1 1 0;1 0 1;0 1 1;1 1 1],'display','off');
