Simulation-Extrapolation: The Measurement Error Jackknife

Simulation - Extrapolation : the Measurement Error

Extrapolation Error

Two kinds of error commonly arise in statistical inference. The most common one is sampling error, arising from small samples. The second is the error arising from unrepresentative samples. Such errors occur in curve-fitting examples when the curves are fitted in one domain and used for prediction in another, which might be referred to as an error of extrapolation. The problem with extrapolatio...

Electromagnetic Tracker Measurement Error Simulation and Tool Design

Electromagnetic tracking is prone to errors due to the distortions caused by the metallic objects situated in the electromagnetic field’s proximity. Hence, a tool with electromagnetic sensors has first to be tested in different environments before it could be safely used in a surgical intervention. Such tests are often succeeded by design iterations meant to minimize the effect of such distorti...

Electromagnetic Tracker Measurement Error Simulation and Tool Design

Developing electromagnetically (EM) tracked tools can be very time consuming. Tool design traditionally takes many iterations, each of which requires construction of a physical tool and performing lengthy experiments. We propose a simulator that allows tools to be virtually designed and tested before ever being physically built. Both tool rigid body (RB) configurations and reference RB configur...

Interval sampling methods and measurement error: a computer simulation.

A simulation study was conducted to provide a more thorough account of measurement error associated with interval sampling methods. A computer program simulated the application of momentary time sampling, partial-interval recording, and whole-interval recording methods on target events randomly distributed across an observation period. The simulation yielded measures of error for multiple combi...
