An alternative to the Engle-Granger tests is the Cointegration Regression Durbin-Watson (CRDW) test of Sargan and Bhargava (1983). The test involves a simple regression of one variable on the other, and the standard Durbin-Watson test on the residuals. Recall the null for the DW test is that the residuals form a nonstationary random walk, whereas the alternative hypothesis is that the residuals...

Abstract This research was conducted to predict the value of carrot production in Karo Regency North Sumatera 2020-2021 by using Autoregression Moving Average model through some testing stages: 1). stationarity data for 2017-2019. In this study, were declared stationary a differentiation process ( 1 st difference ) with an Augmented Dicky-Fuller (ADF) < 0.05. 2). Furthermore, Autocorrelation...

BACKGROUND Preterm birth defined as birth prior to 37 weeks of gestation is caused by different risk factors and implies an increased risk for disease and early death for the child. The aim of the study was to investigate the effect of maternal stress during pregnancy on the risk of preterm birth. METHODS A case-control study that included 340 women; 168 women who gave birth preterm and 172 w...

The topological trace formula is a computation of the Lefschetz number of a Hecke correspondence C acting on the weighted cohomology groups, defined in [GHM], of a locally symmetric space X . It expresses this Lefschetz number as a sum of contributions from fixed point components of C on the reductive Borel Serre compactification of X . The proof uses the Lefschetz fixed point formula of [GM2]....
