Reference coding is also known as treatment codingĬould be ‘full’, but in that case an overcompleteĭesignmatrix is returned. Relevant if you define categorical input variables. ‘quantiles’ (default): heuristic spacing at the quantilesĬfg.codingschema ( string) – default: ‘reference’, could be ‘effects’, this is

‘linear’ : linear spacing with boundary splines at the respective min/max Uf_designmat_spline() after the initial call ofĮxample with multiple formulas: will make both predictorsĬfg.splinespacing ( string) – defines how the knots of the splines should be Custom spline functions are possible by using Splines one uses, the higher the risk of overfittingīut also of course more flexible relations can beįitted. The matlab default, one can specify ‘cat(X)’ so that X is interpreted as aĬategorical variable and therefore dummy/effect-coded.Īlso using spl(Y,5) defines a “non-linear” predictor Parametersįormula in the wilkinson format. The designmatrix is not yet ready to do deconvolution, use The designmatrix.If you add multiple eventtypess+formulas as cell-arrays, this function will iterativelyĬall itself and combine it to one big designmatrix. Input an EEG event structure and you will get an field with uf_designmat ( EEG, varargin ) ¶ Generate Designmatrix out of EEG.event structure and a formula
