Brms truncated normal
WebFeb 4, 2024 · Specifying the initial values for the brms package is really simple. You must declare a value for each parameter in your model, however, you must do so for each Monte Carlo method Markov Chain (MCMC) number. WebJun 24, 2024 · We also consider another scenario when x i is generated from a standard normal distribution N(0,1). We set sample size as n=300, the intercept for both the zero and truncated counts components as β 0 =α 0 =1 to ensure the data are overall zero inflated.
