The Alexander-Govern test was extended to 2-way fixed-effects analysis of variance models. To deal with the impact of violating normality assumptions, variance homogeneity assumptions, or both, the author applied the trimmed mean method to the approximate tests, that is, the Alexander-Govern, Welc...
Numerous papers have shown that the conventional F test is not robust to unequal variances in the one-way fixed effects ANOVA model, and several methods have been proposed for dealing with this problem. Here I describe and compare two methods for handling unequal variances in the two-way fixed...
data. A causal interpretation of twoway fixed effects DD estimates requires both a parallel trends assumption and treatment effects that are constant over time. I show how to decompose the difference between two specifications, and provide a new analysis of models that include time-varying controls...
Compared to other methods tackling factor models such as synthetic controls and matrix completion, our method does not require the number of time periods to grow infinitely. Instead, we draw inspiration from the two-way fixed effect model as a special case of the linear factor model, where a ...
Hence determining the parameter α by a fit to experimental data yields a way to estimate the deviation of the source from a Gaussian or a Cauchy shape. Ideally, the correlation function C2 is investigated as a function of momentum difference in the entire three dimensions, but in case of ...
