Probability Notes and Concepts


  • Prior distribution that incorporates your subjective beliefs about a parameter  
  • Posterior is the result with data
  • Likelihood - Based on the posterior the how ‘likely’ is the data is going to occur
  • Bayesian Linear Regression - The response, y, is not estimated as a single value, but is assumed to be drawn from a probability distribution. Determine the posterior distribution for the model parameters
  • Latent variables as opposed to observable variables), are variables that are not directly observed but are rather inferred (through a mathematical model) 
  • A Bernoulli random variable has two possible outcomes: 0 or 1. A binomial distribution is the sum of independent and identically distributed Bernoulli random variables.
  • Poisson distribution - events occurring in a fixed interval of time or space if these events occur with a known constant rate and independently of the time since the last event
  • Negative binomial distribution describes the number of successes k until observing r failures
Happy Learning!!!
