Sustainability practices have a positive effect on the financial performance of SMEs. We extract ESG-related information for a sample of Spanish SMEs over the period 2012–2022 using tools provided by the Internet Archive to estimate a staggered difference-in-differences model of how the release of...
Robust Regression Methods: Achieving Small Standard Errors When There Is HeteroscedasticityA serious practical problem with the ordinary least squares regression estimator is that it can have a relatively large standard error when the error term is heteroscedastic, even under normality. In practical terms...

In a simple regression analysis, if the standard error of estimate s_{est} = 15 and the number of observations n = 10, then the sum of the residuals squared must be 120. State true or false. True or False Variance Inflation Factors can be used to detect Heteroscedasticity pro...
Data were tested for the corresponding statistical assumptions, which included the Shapiro–Wilk test for normality and Levene’s test for heteroscedasticity. If assumptions were violated the data were analyzed using non-parametric variants of the test. The group comparisons were analyzed using the ...
Violations of homoscedasticity indicate heteroscedasticity, which can affect the reliability of the regression model. Types of Regression There are several types of regression analysis, each suited for different scenarios and assumptions. Understanding these regression types enables data scientists to build ...

Heteroscedasticity in both error terms can be implemented, in addition to heterogeneity in the truncated mean parameter in the case of the truncated normal and lognormal distributions. In addition, in the case of the truncated normal distribution, the scaling property can be estimated. The main fun...
