Specification Testing for Dyadic Regression Models

Ulrich Hounyo, Jiahao Lin, Xiaojun Song

This paper develops omnibus specification tests for linear conditional-mean models with undirected dyadic data. We establish a uniform projection theorem that reduces the dyadic pr…

Supervised Mixed-Frequency Learning for Macro-Financial Forecasting When Factors are Weak

Ulrich Hounyo, Zhendong Li

Factor-MIDAS regressions forecast a low-frequency target by extracting common factors from a large panel of high-frequency predictors via principal component analysis (PCA). While…

Identification and Information after Nuisance Projection

Ulrich Hounyo

Empirical work often removes fixed effects, latent factors, or high-dimensional controls before estimating structural relationships. These transformations reduce confounding but ma…

When Does Heteroskedasticity Matter? A Contrast-Specific Theory of Robust Inference

Ulrich Hounyo

Conventional heteroskedasticity diagnostics ask whether the conditional variance of the regression disturbance varies with covariates. This paper asks a different question: when do…

Estimation and Inference for the -Quantile of Individual Heterogeneous Coefficient

Antonio F. Galvao, Ulrich Hounyo, Jiahao Lin

This paper proposes estimation and inference procedures for quantiles of the heterogeneous individual-specific coefficients in panel data. Unlike conventional panel quantile regres…

Robust Inference for Dyadic Data with Dependent Ordered Nodes

Ulrich Hounyo, Jiahao Lin, Xiaojun Song

Dyadic regression models are commonly analyzed under the conventional dyadic dependence framework, where two observations may be dependent only if the corresponding dyads share a n…
