- Entrepreneurship in times of economic stress: unraveling the U-shaped relationship between the internality of causal attributions and growth(2024) GUILHERME FOWLER DE AVILA MONTEIRO; RINALDO ARTESPurpose – This paper examines the relationship between entrepreneurs’ internality of causal attributions and firm growth during an economic crisis. We propose a U-shaped relationship between the two variables, arguing that the highest-growth entrepreneurs are those with either the highest or lowest levels of internal attribution (IA) during such periods.
- The circular quantile residual(2023) Andrade, Ana C.C.; Pereira, Gustavo H.A.; RINALDO ARTESCircular-linear regression is often used to model the relationship between a circular dependent variable and a set of linear predictor variables. It is used in many areas such as meteorology, biology, and medicine. For checking model adequacy, it is desirable to use residuals that are approximately standard normally distributed. Most of the residuals used in circular regression models do not meet this requirement and are used especially for outlier identification. Other residuals are limited to the von Mises regression models. An asymptotically standard normally distributed residual that can be used for any parametric circular-linear regression model is introduced. Monte Carlo simulation studies suggest that the distribution of this residual is well approximated by the standard normal distribution in small samples. To study the behavior of this residual, two regression models are introduced, and two applications are used to show that the proposed residual can detect model misspecification.
