Population parameter notation
WebApr 10, 2024 · The parameter θ (> 0) denotes the inertia for maintaining the previous instructions. The inertia parameter is expected to take positive values to model how the exit choice model is likely to revise the previous exit allocations. It models the pedestrians’ tendency to maintain the previous exit-choice decisions. WebLater in the article, you’ll see the some of the more frequently used ones. Let's take a look at some of the terminology and notation used. The result of a point estimation of a parameter is a single value, usually referred to as the estimator, and it will usually have the same notation as the population parameter it represents plus a hat '^'.
