The concept of square roots dates back thousands of years, and despite the technological advances that offer quick calculations, it’s still essential to understand how to calculate a square root ...

The cube root of a number is a value that, when multiplied by itself three times, results in the original number. For example, the cube root of 27 is 3 because 3 * 3 * 3 = 27. Calculating the cube ...

This paper develops a test of the unit root null hypothesis against a stationary threshold process. This testing problem is nonstandard and complicated because a parameter is unidentified and the ...
