Likert pain score modeling: a markov integer model and an autoregressive continuous model
Clinical Pharmacology & Therapeutics, 04/06/2012
Plan EL et al. – In both models, the score baseline was estimated to be 6.2 and the placebo effect to be 19%. Developed models similarly retrieved consistent underlying features of the data and therefore correspond to platform models for drug effect detection. The integer model was complex but flexible, whereas the continuous model can more easily be developed, although requires longer runtimes.
