Q: What is the difference between least squares method and linear regression?

Common Misconceptions

One common misconception about the least squares method is that it only works for linear relationships. While it's true that linear regression is a specific application of the least squares method, the algorithm can be applied to non-linear relationships as well. Another misconception is that the least squares method is only suitable for large datasets. However, the algorithm can be applied to small datasets as well, as long as the model is correctly specified.

A: The least squares method is generally suitable for continuous data, but may not perform well with categorical or time-series data.
