This tells us the minimum, median, mean, and maximum values of the independent variable (income) and dependent variable (happiness): Again, because the variables are quantitative, running the code produces a numeric summary of the data for the independent variables (smoking and biking) and the dependent variable (heart disease): Scribbr editors not only correct grammar and spelling mistakes, but also strengthen your writing by making sure your paper is free of vague language, redundant words, and awkward phrasing. Pearson. Each entity has its own individual characteristics that may or may not influence the predictor variables (for example, being a male or female could influence the opinion toward certain issue; or the political system of a particular country could have some effect on trade or GDP; or the business practices of a company may influence its stock price). If this doesn't work, you may need to edit your .htaccess file directly. Again, the p value is large so do not need to use time-fixed effects in this model.
