    In Section of R. S. Tsay, Analysis of Financial Time Series, I read: The basic idea behind volatility study is that the series {r_t} is either serially uncorrelated or with minor lower order serial correlations, but it is a dependent a little further: it seems that the returns are indeed serially .   The Durbin Watson statistic is a test for autocorrelation in a data set. The DW statistic always has a value between zero and A value of means there is .

Recent empirical evidence suggests that reversing current account balances imply costly adjustment processes leading to reduced economic growth. Using large panel data sets to analyze determinants and costs of reversals asks for controls of heterogeneity among countries. This paper contributes a Bayesian analysis, which allows a parsimonious yet flexible handling of country.

      Time series data often have errors that are serially correlated, that is, correlated over time. Panel data have errors that can be correlated within unit (e.g. individuals), within period. Conventional regression-based strategies to address correlated errors Cluster-consistent covariance matrix estimator to adjust standard errors. An alternative approach for addressing the correlation of errors across observations is the Newey-West procedure (Newey and West, ). This procedure was initially designed to account for a serial correlation of unknown form in the residuals of a single time series.

assume that the quantities a;b, etc. have errors which are uncorrelated and random.

It is common for some factors within a causal system to be dependent for their value in period t on the values of other factors in the causal system in period t − 1.

However, frequently data are serially correlated in climatological applications with the result that the t test in its standard form is not applicable. The usual solution to this problem is to scale the t statistic by a factor that depends upon the equivalent sample size n e.

I would like to find the R implementation that most closely resembles Stata output for fitting a Least Squares Regression function with Heteroskedastic Corrected Standard Errors.

Specifically I would like the corrected standard errors to be in the "summary" and not have to do additional calculations for my initial round of hypothesis testing.

gle networks. In particular, systems of interdependent networks often undergo abrupt first-order percolation transitions induced by cascad-ing failures.

Here we present an overview of recent developments and significant findings regarding interdependent networks and networks of networks. 1 Background: From Single Networks to Networks of Networks.

Introduction. Globalization, as a complicated process, is not a new phenomenon and our world has experienced its effects on different aspects of lives such as economical, social, environmental and political from many years ago –.Economic globalization includes flows of goods and services across borders, international capital flows, reduction in tariffs and trade barriers, immigration, and.

1 Cascading Failures in Interdependent Systems: Impact of Degree Variability and Dependence Richard J. La Abstract—We study cascading failures in a system comprising interdependent networks/systems, in which nodes rely on other nodes both in the same system and in other systems to perform their function.The lagged dependent variable approach makes it easier for researchers to examine dynamics and allows for natural generalizations in a manner that the serially correlated errors approach does not.Any discussion of interdependence must first seek to establish what is meant by that term.

A number of different definitions of interdependence exist which use the term as an analytical tool for examining recent and significant changes in the structures of international relations 1 and which identify it variously as a phenomenon, a state and a concept.
