Estimation of the regression slope by means of Gini's cograduation index

D. M. Cifarelli

The simple linear model $$Y_i=\alpha +\beta x_i+{\epsilon }_{i}i=1,2,\dots ,N\ge 2$$ is considered, where the $x_i$'s are given constants and ${\epsilon }_1,{\epsilon }_2,\dots ,{\epsilon }_N$ are iid with cont…
