Analog vs. Digital Signals
What is the difference between analog and digital? In analog signals (e.g., in the transmission of conventional radio or television), the electrical signal that is transmitted through magnetic waves bears a striking resemblance to the sound or image that resulted, hence the name “analog,” which comes from “analogue.” Digital signals, however, bear no resemblance to the stimulus that created them and consist of a combination of ones and zeros (digits). The main advantage

Principal Component Analysis and Cluster Analysis
Principal Component Analysis (PCA)
PCA is a mathematical method that uses an orthogonal transformation to convert a set of correlated variables into uncorrelated variables called the principal components. The first component has the highest variance (it captures the most variation in the data), followed by the second, third, and so on. The components must be uncorrelated (remember orthogonal direction). Normalizing data becomes extremely important when the predictors are measured in different units.
