Landmark analysis at the 25-year landmark point.
This statistical primer presents the landmark analysis method, exploring its appropriate use and interpretation while recognizing its limitations. This observational method is used for comparing time-to-event outcome between groups determined during study follow-up. The goal of the landmark method is to estimate in an unbiased way the time-to-event probabilities in each group conditional on the...

متن کاملThe Landmark Spider: Weaving the Landmark Web
Landmarks play an important role when humans navigate through foreign environments (Lynch, 1960; May, Ross, Bayer, and Tarkiainen, 2003). For example, trying to find the way is much easier if the navigator can rely on a description of the route based on well-recognizable objects in the environment, instead of navigating solely on the basis of street names and metric directions (Tom, and Denis, ...
متن کاملLandmark Analysis Software Review
We have studied a number of software tools dealing mainly with morphometric analysis of images reccommended by our collaborators. The study not only helps us to be aware of the existing tools in the field, but also points the way towards developing our own software. The aim is to cover the project’s requirements based on use in scientific analyses.
متن کاملAutomatic Landmark Generation for Point Distribution Models
Point Distribution Models (PDMs) are statistically derived flexible templates which are trained on sets of examples of the object(s) to be modelled. They require that each example is represented by a set of points (landmaiks) and that each landmark represents the same location on each of the examples. Generating the landmarks from 2D boundaries or 3D surfaces has previously been a manual proces...
