Naive Bayes Classifiers
In lecture, we learned about Bayes’ Theorem, an important result in probability theory that links the probability of an event happening given that a related event has happened to the probability of that related event happening. Bayes’ Theorem can be written formally as follows: where P(A | B) is the probability that event A happens […]
How does online advertising work?
Link to the online article: http://www.practicalecommerce.com/articles/129726-Google-AdWords-Ad-Rank-Impacts-PPC-Success In class, we learned that having the highest bid will always guarantee the first advertisement spot.

Game Theory: Donald Trump’s Campaign Strategy
In Steven Bram’s article: “Here’s how game theory helps explain Donald Trump’s strategies” he highlights Republican Party Nominee: Donald Trump’s campaign strategy and why it is working.

Consumers and users alike are curious about how much an advertisement actually costs on Facebook, and unsurprisingly, it depends […]
Day to Day Bayes Theorem
In lecture, we have been discussing Bayes theorem as a tool for examining decision making. Bayes theorem is not just an equation used by statisticians and it is not even limited to professional use! Bayes theorem can be applied in day to day decisions and can often provide a different outlook on events. As described […]
Bargaining power: Nike
This article was about the market power of Nike based upon Five Forces. These forces are Competitive rivalry or competition (Strong Force), Bargaining power of buyers or customers (Moderate Force), Bargaining power of suppliers (Weak Force), Threat of substitutes or substitution (Moderate Force), and Threat of new entrants or new entry (Weak Force).
