Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The least-squares method of cost estimation involves using mathematical regression techniques to calculate the slope and intercept of the best-fit line for the costs used in estimation.

Various books and articles have highlighted problems inherent in a least squares analysis of disproportionate cell data. The method of unweighted means, an approximate but much simpler technique, was ...
