On the distribution of isometric log-ratio transformations under extra-multinomial count data
Noora Kartiosuo, Joni Virta, Jaakko Nevalainen +2
Compositional data arise when count observations are normalised into proportions adding up to unity. To allow use of standard statistical methods, compositional proportions can be…
Stationary subspace analysis based on second-order statistics
Lea Flumian, Markus Matilainen, Klaus Nordhausen +1
In stationary subspace analysis (SSA) one assumes that the observable p-variate time series is a linear mixture of a k-variate nonstationary time series and a (p-k)-variate station…
On the number of signals in multivariate time series
Markus Matilainen, Klaus Nordhausen, Joni Virta
We assume a second-order source separation model where the observed multivariate time series is a linear mixture of latent, temporally uncorrelated time series with some components…
