Seizure (Ictal)—EEG Characteristics in Subgroups of Depressive Disorder in Patients Receiving Electroconvulsive Therapy (ECT)—A Preliminary Study and Multivariate Approach

Table 4

Results of linear discriminant analysis using variables from the post ECT EEG frequencies of the 1st seizure. The correct number of number of individuals in respective subgroups of depressed (True group = patients) is on top of the table. The number of classified individuals according to the discriminant function is shown in the left margin (assigned to group = classified). Subgroups of depression: psychotic depression (PD), bipolar depression (BD), and unipolar depression (UD).

Assigned to group	True group

PD	7	1	0	8
UD	0	18	0	18
BD	0	1	6	7
Total	7	20	6	33
𝑁 correct	7	18	6
