Regression Estimation (from Lohr‚ Ex 3.6.4) Foresters want to estimate the average age of tress in a stand. Determining age is cumbersome because one needs to count the tree rings on a core taken from the tree. In general‚ though‚ the older the tree‚ the larger the diameter‚ and diameter is easy to measure. The foresters measure the diameter of all 1132 tress and find that

Uniform linear acceleration Introduction This topic is about particles which move in a straight line and accelerate uniformly. Problems can vary enormously‚ so you have to have your wits about you. Problems can be broken down into three main categories: Constant uniform acceleration Time-speed graphs Problems involving two particles Constant uniform acceleration Remember what the following variables represent: t = the time ; a = the acceleration ; u = the initial speed ; v = the final
