Read MoreUnderstanding Functions and Their Properties
A function is a relation between two variables, such that for each value of the first variable (magnitude), there corresponds one and only one value of the second. The first variable is known as the independent variable. The dependent variable is the one whose values are determined from the values of the independent variable.
Key Concepts of Functions
- The domain of a function is the set of values of X for which there is a corresponding Y value (image).
- The range of a function is the set of Y values
Compustat Capitalization: Calculation and Applications
Unit 3: Compustat Capitalization
1. Calculating Capitalization in Compustat
We consider (1 + i)n a capitalization selection factor. In the case of Compustat capitalization, this factor shifts a given amount from one moment to a later one.
S (1 + I)NL-Factor updates the Compustat capitalization, shifting a given amount from one moment to an earlier one. That is, it shifts negative translations of capital.
2. Calculating Initial Capitalization in Compustat
Regardless of the capitalization regime applied,
