A time series with a unit root or fractional unit root can be miscategorized in stationarity tests if the series has structural breaks. This finding is tested on Finnish and Swedish party popularity series. The composition and nature of popularity series provide reasons to assume fractional dynamics. The years included, 1987-2001, offer several reasons for the existence of structural breaks. Th...
The strain-promoted "double-click" (SPDC) reaction using Sondheimer diyne, a novel convergent method conjugating three molecules spontaneously, has enabled us to readily modify an azido-biomolecule with a small reporter azido-molecule.
This study tests for the stationarity of aggregate output (GDP at factor cost) and its three major components, namely GDP agriculture, GDP industry and GDP services in the presence of structural breaks during 1950-51 to 2011-12. Results indicate that (i) the GDP has three break points; (ii) GDP agriculture contains one while the GDP industry and GDP services contain four breaks each; and (iii) ...
This paper develops a new model and estimation procedure for panel data that allows us to identify heterogeneous structural breaks. We individual heterogeneity using grouped pattern. For each group, we allow common breaks in the coefficients. However, number, timing, size of these can differ across groups. develop hybrid fixed effects approach adaptive group fused Lasso. show our method consist...
