The most simple and beginner friendly book for learning "Data Structures in C"
-it's super beginner friendly
-it's that book that I have used for my college studies
-this is my first book for data structures
-it is written by Indian Author
-it's just mine experience, so use it according to your preferences
-because many people are asking, that's why I am telling my recommendation.
Bayesian data analysis is a fundamental concept in data science. But it took me 2 years to understand its importance. In 2 minutes, I'll share my best findings over the last 2 years exploring Bayesian Modeling. Let's go.
1. Why Bayesian Data Analysis? Bayesian modeling is a powerful tool in statistics and data science, especially where traditional approaches fall short. It avoids arbitrary assumptions and provides distributions of possible values instead of just point estimates.
2. Bayes Theorem: Bayesian modeling is based on Bayes’ theorem. Bayes' Theorem provides a mathematical formula to update the probability for a hypothesis as more evidence or information becomes available. It describes how to revise existing predictions or theories in light of new evidence, a process known as Bayesian inference.
3. Simplification of Bayes’ Theorem: Since X (data) is not dependent on θ (the model) and can be hard to calculate, Bayes’ theorem is often simplified to P(θ|X) ∝ P(X|θ) × P(θ), meaning the posterior distribution is proportional to the likelihood times the prior.
4. From Bayesian Theorem to Bayesian Modeling: Bayes’ Theorem provides a process for constructing a Bayesian model. Combining key ingredients: Likelihood and Prior distributions to produce Posterior Distributions.
5. Calculating the Posterior Distribution: There are two main methods: direct calculation using complex equations, and simulation methods which create samples from the posterior distribution for summarizing information about parameters. Many software programs like PyMC, Brms, and Stan use sampling methods such as Markov Chain Monte Carlo (MCMC).
6. Advantages of Bayesian: The Bayesian approach allows for direct inclusion of prior knowledge, transparency in modeling steps, and provides broad information about the problem, including risks, uncertainty, and variability.
7. Business Cases: Any time knowledge of uncertainty is a business requirement, Bayesian modeling can benefit the business. This includes Demand Forecasting, Pricing Strategy Optimization, Customer Analysis, Credit Scoring and Financial Modeling. Businesses need to know not only a point estimate but the risk or confidence of the prediction.
