That means you can click on it, and Stata will refer you to an explanation. For example this happens when you have clustered standard errors and only few clusters. Similar issues arise with survey data, but this is all documented. Best Daniel

Multiple Linear Regression: -4th: If we run the regression for 3 variables at the same time, we will have different numbers if we do a simple linear regression for each one. -5th: To understand if the relationship is linear, we need to calculate a square term 2 (tot. WitrynaThe Brown-Forsythe test is conceptually simple. Each value in the data table is transformed by subtracting from it the median of that column, and then taking the absolute value of that difference. One-way ANOVA is run on these values, and the P value from that ANOVA is reported as the result of the Brown-Forsythe test. How …

You can compare a sample mean to a hypothesized or target value using a one-sample t-test. You can compare the means of two groups with a two-sample t-test. If you have two groups with paired observations (e.g., before and after measurements), use …
