Note: Table of parameter estimates. Each column represents a group LASSO model of an EEG outcome variable. Parameter estimates less than 0.001 were shortened to 0.000 to save space. ~p <.10, *p <.05, **p <.01, ***p <.001. Variables with no symbol were retained by group LASSO but not significant in the final model. A non-significant model means that independent variables did not improve model fit over an intercept-only model. Only variables chosen by group LASSO are presented. Reference groups are as follows—Stimulus: Stimulus 1, Sex: Male, Group: TD, System: EGI. ITC, intertrial phase coherence; DS, deletion size; Stim, stimulus; PMS, Phelan McDermid Syndrome
