Web4 de sept. de 2024 · If you do a linear regression of volume as a function of girth ( lm (formula = Volume ~ Girth, data = trees)) you get a linear model with a negative intercept. The fit isn't bad (even though a quadratic model would be better) with R 2 = 0.93. You could use it to get reasonable predictions of the volume of such a tree in terms of its girth. Web6 de abr. de 2024 · The intercept, β 0, can then be interpreted as a log density estimate in a single hectare of nonforested terrain.
