Affine model estimation
WebMar 25, 2024 · I have two images that I want to compute the affine motion model parameters. The model that I use is x ′ = a 1 x + a 2 y + a 3 y ′ = a 4 x + a 5 y + a 6 To calculate those 6 parameters, I picked 6 points (overdetermined system) between two images, and calculated those parameters by using MATLAB (A = X\X_primes). WebNov 3, 2024 · Affine term structure models are widely used for studying the relationship between yields on assets of different maturities. However, it can be a helpful tool for the construction of fixed-income portfolios. The monitoring of these bond portfolios is of great importance for the investor. The purpose of this work is twofold. Firstly, we construct and …

WebTraditional graphical models for continuous data are inappropriate for network inference of count data. We consider the Poisson log-normal (PLN) graphical model for count data and the precision matrix of the latent normal distribution represents the network. We propose a two-step method PLNet to estimate the precision matrix. PLNet first ...
