In this paper, we investigate whether incorporating common factors of CPI sub-aggregates into forecasting models increases the accuracy of forecasts of inflation. We extract factors by both static and dynamic factor models and then embed them in ARMA and VAR models. Using quarterly data of Iran’s CPI and its sub-aggregates, the models are estimated over 1990:2 to 2008:2 and out of sample ...

In this paper we propose the application of the original, superlative price index formula for the measurement of commodity substitution bias associated with Consumer Price Index (CPI). In our simulation study we compare CPI bias values calculated by using the original price index formula with those calculated on the basis of some known, superlative price indices.

BACKGROUND Pulmonary artery vasoconstriction and vascular remodeling contribute to a sustained elevation of pulmonary vascular resistance and pressure in patients with pulmonary arterial hypertension (PH), an often fatal hemodynamic disease. The effect of docosahexaenoic acid monoacylglyceride (MAG-DHA) and the role of the 17 kDa protein kinase C-potentiated inhibitor protein (CPI-17) were dete...

The paper deals with issues that have been found important for the treatment of financial services in Swedish price indices. In particular the definition of the unit transaction for fund and stock-brokering services with charge proportional to transaction value is crucial. Such services have more than a negligible extent in Sweden, also for consumers, and different definitions of the unit trans...

Activation of hepatic stellate cells (HSCs) results in cirrhosis and portal hypertension due to intrahepatic resistance. Activated HSCs increase their contraction after receptor agonist stimulation; however, the signaling pathways for the regulation of contraction are not fully understood. The aim of this study was to elucidate the change in contractile mechanisms of HSCs after cirrhotic activa...

OBJECTIVE Conventional hemodynamic indexes (cardiac index (CI), and pulmonary capillary wedge pressure) are of limited value in the diagnosis and treatment of patients with acute congestive heart failure (CHF). PATIENTS AND METHODS We measured CI, wedge pressure, right atrial pressure (RAP) and mean arterial blood pressure (MAP) in 89 consecutive patients admitted due to acute CHF (exacerbate...
