Latent factor models for large and mixed-frequency data in finance and macroeconomics

Rubin, Mirco ; Gagliardini, Patrick (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2016 ; 2016ECO002.

My thesis considers new latent factor models, and their estimation methodologies, suitable for settings relatively unexplored in the econometric literature as (i) a nonlinear model for the joint dynamics of a large cross-sectional distribution of asset returns, and the persistence of the ranks of the individuals inside it; (ii) approximate linear latent factor models for large panels of...

Redundancy or heterogeneity in the electric activity of the biceps brachii muscle? Added value of PCA-processed multi-channel EMG muscle activation estimates in a parallel-fibered muscle

Staudenmann, Didier ; Stegeman, Dick F. ; Dieën, Jaap H. van

In: Journal of Electromyography and Kinesiology, 2013, p. -

Conventional bipolar EMG provides imprecise muscle activation estimates due to possibly heterogeneous activity within muscles and due to improper alignment of the electrodes with the muscle fibers. Principal component analysis (PCA), applied on multi-channel monopolar EMG yielded substantial improvements in muscle activation estimates in pennate muscles. We investigated the degree of...
