Examining the new cognostics
Investigate the output of the plot you just created (now with all countries and with as_plotly = TRUE
) and interact with the cognostics to answer the question: Which country has the poorest linear model fit according to the fraction of variance explained by the model? Note that this quantity is known as "R-squared", and that cognostics associated with the linear model fit begin with _lm
.
