CAIA QUESTIONS WITH SOLUTIONS 2024 An asset-pricing model that attempts to explain how investors should behave is a(n): normative model. Normative models attempt to explain how investors should behave. Positive models attempt to explain how investors do behave. Theoretical models use assumptions and logic, while empirical models are based on historically observed behavior. Henry Thompson examines a sample of returns for a private equity fund and finds that the sample excess kurtosis ...

median vs IQR skewed data uses these for center and spread Histogram - when to use Based on the shape of the distribution, uses mean + standard deviation OR median + IQR to describe center and spread - Larger data sets; shows shapes of distribution and potential outliers; ignores the individual data valuesl Histogram Skewed right Not a symmetric distribution, the tail is on the right Standard Deviation Rule 68% of the data are within 1 standard deviation, 95% are...
