In monotonicity: Test for Monotonicity in Expected Asset Returns, Sorted by Portfolios

Description

demo_returns is a sample of asset returns from July 1963 to December 2001 of all stocks listed on the NYSE and is computed as follows: at the begiinig of each month, tocks are sorted into deciles using estimates of beta based on the past year of daily returns, and value-weighted portfolios are formed. two tests from Wolak (1989, JoE) of inequality constraints in linear econometric models.

Usage
