arviz

问题 I try to predict the outcome of soccer games based on the number of goals scored and I use the following model: with pm.Model() as model: # global model parameters h = pm.Normal('h', mu = mu, tau = tau) sd_a = pm.Gamma('sd_a', .1, .1) sd_d = pm.Gamma('sd_d', .1, .1) alpha = pm.Normal('alpha', mu=mu, tau = tau) # team-specific model parameters a_s = pm.Normal("a_s", mu=0, sd=sd_a, shape=n) d_s = pm.Normal("d_s", mu=0, sd=sd_d, shape=n) atts = pm.Deterministic('atts', a_s - tt.mean(a_s)) defs =

问题 Hello! After running a model for a simple linear regression model in pymc3, I'm trying to do a plot. As you can see both plots show the "posterior predictive mean score", but I was wondering whether can I plot this distribution around the "posterior predictive mean score" (not around "observed score"), in arviz, similar to what is shown in the first figure? Both figures were made using the same data: Score <- c(78.93,58.2,67.47,37.47,45.65,32.92,29.97) Drugs <- c(1.17,2.97,3.26,4.69,5.83,6,6

问题 In Google's colaboratory, installed arviz then did import arviz without error, but in a code cell, pm.plot_posterior(samples) gets error: arviz not installed. Trying to plot Bayesian code pm.plot_posterior(samples) I expect a plot 回答1: Install Arviz prior to importing PyMC3 , otherwise it apparently cannot find it. In your case, simply restarting the runtime ( Runtime > Restart runtime... ) should get it working. 回答2: Hi did you try adding the cell magic %matplotlib inline ? This may be an
