SMOOTHING TECHNIQUES Several techniques are available to forecast time-series data that are stationary or that include no significant trend‚ cyclical‚ or seasonal effects. These techniques are often referred to as smoothing techniques because they produce forecasts based on “smoothing out” the irregular fluctuation effects in the time-series data. Three general categories of smoothing techniques are presented here: • Naive forecasting models are simple models in which it is assumed that the

Biophysical Ecology Abstract: There are many patterns that can be observed throughout our environment. In this experiment‚ the temperatures of organisms in a biophysical environment were analyzed to see if a pattern could be recognized that was related to the behavior of an ectotherm. An ectotherm is an organism that relies on the environment to regulate its body temperature. Organisms such as Pseudemys (turtles) and Lacertilia (lizards) are examples or ectotherms.
