Moving on forward in
the book, these days were about Categorical Variables, significance testing
(t-ratios, F-ratios, ANOVA) moving on to variable selection throughout which I
struggled to maintain interest. However, this was extremely crucial knowledge
and stressed the importance of intuition to support the math. Luckily, I was
able to sum this up through an example on modeling Stock Liquidity using
various performance measures.
The case study begins through defining the following
criteria through which investors choose their stocks;
- Expected Return;
- Riskiness (Volatility);
- Length of Time of Investment (Varies for Growth and Income Stocks);
- Liquidity (Ease through which a stock could be sold, measured through its VOLUME in a stock market)
