r-squared

Having said that, the relationship is not very strong r-squared=.20, and there are certainly a number of exceptions to the general pattern.

There is hardly any relationship r-squared=.07, and slight pattern that does exist is nonsensical, indicating that Obama's best strategy would be to increase unemployment as much as possible.

They then go on to add the product of the two variables to the specification, finding that the original two variables become insignificant while their interaction is positive and significant (and the r-squared rises).

His complaints are probably better aimed at Philosophy or History programs — unless he can tell us how Burke and Adams can contribute to rational choice, formal models, and higher r-squared values.

Even if you're just adding the trend as a smoother (and a moving average would almost always be a better way to smooth time series data, while a lowess would be the more normal way to smooth a scatterplot), selecting one by the r-squared criterion (or any other residual variance criterion) wouldn't necessarily make sense.

Thus the r-squared correlation between IQ and income is somewhere in the range of 10%.

When I reran the same regression but dropped the “onepar” variable, the adjusted r-squared increased slightly.
