Fig. 2From: Exponential distribution of total depressive symptom scores in relation to exponential latent trait and item threshold distributions: a simulation studyProcess model of a binary scale of depressive symptoms. Two sets of random numbers, representing individuals with a specific degree of a depressive symptom’s latent trait and a specific threshold for each depressive symptom, are generated. If the random number of the depressive symptom’s latent trait is greater than that of the specific item’s threshold, the specific symptom is considered presentBack to article page
