Fisher matrix analysis
WebJun 14, 2016 · Fisher Linear Dicriminant Analysis. The implemented function supports two variations of the Fisher criterion, one based on generalised eigenvalues (ratio trace criterion) and another based on an iterative solution of a standard eigenvalue problem (trace ratio criterion). The later implementation, is based on. WebThe purpose of this project was to conduct a Fisher matrix analysis of a rotational velocity field-based model of a weak gravitational lensing survey. This was to see how well this new model can constrain the lensing parameters, which in turn can help constrain properties of the lensing mass. It was found that this new model
