Bayes' rule correct answers Given some observed data x, the posterior probability that the parameter Θ has the value θ is p(θ|x) = p(x|θ)p(θ)/p(x), where p(x|θ) is the likelihood, p(θ) is the prior probability of the value θ, and p(x) is the marginal probability of the value x. conditional probability correct answers The probability that the value of one random variable Θ has the value θ given that the value of another random variable X has the value x; written as p(Θ=θ|X=x) or p...

Chapter 11 Analysis of Quantitative Data 1) Explain how a researcher codes, enters, and cleans data so that it can be used for statistical analysis. What procedures are involved in each of these steps? Answer: • Coding the data: Data coding means systematically reorganizing raw numerical data into a format that is easy to analyze using computers; rules are developed whereby certain numbers are assigned to the attributes of each variable. • Entering data: Data are entered in a grid f...

What is PCA? (5 key points) Principal Component Analysis is a statistical technique used for dimensionality reduction, crucial when dealing with high-dimensional data in machine learning. It works by transforming original variables into new ones, called principal components, which are linear combinations of the original variables. Key Points: 1. Principal Components: Principal components are the directions in the data that maximize variance. The first principal component captures the most...
