Boston University; Department of Economics ECONOMICS ADVANCED ECONOMETRICS I Spring Professor Pierre Perron Professor Zhongjun Qu The aim of the course is to develop familiarity with a wide range of statistical and econometric techniques that have proved to be useful in applied contexts. Jan 10, · Intensity regression models provide flexible and powerful tools for studying one of the most basic questions of credit risk modeling: Which observable variables influence the default risk of corporations? Consequently, the models are useful for risk management of loan portfolios by providing a strong statistical basis for credit fdn2018.com by: 2.

dynamic regression models of market on accounting values are estimated in levels and returns, using a selected panel of 30 of some of the largest long-lived USA firms over a 50 year period. Multiplicative models of levels data produce markedly improved statistical specifications compared to additive forms. An Introduction to Modern Econometrics Using Stata can serve as a supplementary text in both undergraduate- and graduate-level econometrics courses, and the book’s examples will help students quickly become proficient in Stata. The book is also useful to economists and businesspeople wanting to learn Stata by using practical examples.

One important form of mis-specification occurs when the true model is dynamic and the investigator wrongly assumes that it is static. The estimated residuals from a regression equation are then likely to show some degree of autocorrelation. In such cases, the Durhin-Watson d statistic (2) gives ample warning that something is wrong.
Rut Cited by: 1. This requires avoiding all the sources of misspecification mentioned above. One approach is to start with a model in general form that relies on a theoretical understanding of the data-generating process.
Then the model can be fit to the data and checked for the various sources of misspecification, in a task called statistical model validation. Structural break tests for regression models are sensitive to model misspecification. We show—analytically and through simulations—that the sup Wald test for breaks in the conditional mean and variance of a time series process exhibits severe size distortions when the conditional mean dynamics are misspecified.
We also show that the sup Wald test for breaks in the unconditional mean Author: Alaa Abi Morshed, Elena Andreou, Otilia Boldea.

Downloadable. Linear cointegration is known to have the important property of invariance under temporal translation. The same property is shown not to apply for nonlinear cointegration. The requisite limit theory involves sample covariances of integrable transformations of non-stationary sequences and time translated sequences, allowing for the presence of a bandwidth parameter so as to Cited by: This paper discusses the issue of model misspecification and model-free methods in dynamic panel data analysis.

Generalized Information Matrix Tests (GIMTs) have recently been used for detecting the presence of misspecification in regression models in both randomized controlled trials and observational studies.
In this paper, a unified GIMT framework is developed for the purpose of identifying, classifying, and deriving novel model misspecification tests for finite-dimensional smooth probability fdn2018.com by: 5.

9 Assessing Studies Based on Multiple Regression. The majority of Chapter 9 of the book is of a theoretical nature. Therefore this section briefly reviews the concepts of internal and external validity in general and discusses examples of threats to internal and external validity of multiple regression models.

Tests for qualitative and limited dependent variable.Generalized linear regression models are the global framework of this book, but we shall only introduce them.
Chapter 1 is dedicated to (standard and Gaussian) linear regression models. Despite just being a special case of generalized linear models, linear models need to be discussed separately for a .Most linear factor models used in portfolio risk management employ one of three basic estimation procedures: (1) least squares regression on time-series data, (2) least squares regression on fundamental accounting variables, or (3) factor analysis.
These procedures are often referred to as economic, fundamental, and statistical factor models.
