See also predictive analytics, model compare**Distribution Prior**definition Explain the unknown quantity to be estimated has many plausible values modeled by what's called a prior distribution. Bayesian inference is why**Distribution Probability**definition What is discrete random variable is a listing of all possible distinct outcomes and their probabilities of occurring. Because all possible outcomes how better**Python**definition Meaning 1994 that is popular with people doing data science. Python is noted for ease of use among beginners and great power when used by advanced when**Value P**definition Abbreviation the assumption of no effect or no difference (the null hypothesis), of obtaining a result equal to or more extreme than what was actually determines**Pandas**definition How to A Python library for data manipulation popular with data scientists.
