The density of a substance at 0°C is 10 g/cc and at 100° C, its density is 9.7 g/cc. The coefficient of linear expansion of the substance is
Initial temperature ( T1 ) = 0o C
Initial density ( ρ1 ) = 10 g/cc
Final temperature ( T2 ) = 100oC
Final den... |
When the beacon chain is not finalising it enters a special "inactivity leak" mode.
Attesters receive no rewards. Non-participating validators receive increasingly large penalties based on their track records.
This is designed to eventually restore finality in the event of a permanent failure of large numbers of valida... |

Post 8: Sampling the variance of person ability with a Gibbs step
The Bayesian 2PL IRT model we defined in Post 1 set a hyper-prior on the variance of the person ability parameters. This post implements the sampler for this parameter as a Gi... |
