end of life

the variable period during which dying individuals and their families, friends, and caregivers face issues related to the imminent prospect of death. The end-of-life concept is a way of considering the total context of an approaching death, rather than medical factors only. End-of-life issues include decisions relating to the nature of terminal care (hospice or traditional), whether to resuscitate, the distribution of property and assets, funeral and memorial arrangements, and leave taking and possible reconciliations with family and friends. See also advance directive; informed consent.

best fit

best fit

the theoretical pattern that best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values. On a scatterplot, a line of best fit provides a visual depiction of this pattern, allowing extrapolation to values not part of the original data set. It is important to note that the best-fitting pattern is not necessarily the one that generated the observed data, as other patterns not considered may provide a superior fit.
