A Leslie Matrix is a square matrix used to determine population growth over time and the stable age distribution for that population.

What is the file drawer problem?
|
For example, studies failing
to find a significant effect of treatment are less likely to be published, a problem that is sometimes called the ‘file-drawer problem’ (Rosenthal 1991; Arnqvist & Wooster 1995). As a consequence, a summary of only published results would be expected to show more of an effect than really exists (Palmer 1999, 2000). |
