Table 4: Coefficients of multiple linear regressions. The model for the second dependent variable (Favorite Pubs.) was also significant (F = 311.278, \(p\)-value \(<\) 0.0001), adequately explaining the variance of this variable with values of R = 0.931 and R2 = 0.917, respectively. Therefore, this second regression revealed the influence of the variables \"Original Tweets\", \"Pub. 8:00 to 10:00\", and \"Gender equality\" on the recognition obtained, through favorites, of the content published by the organization (see Table 4). To corroborate the validity of the above regressions, the authors analyzed the residuals of both using the Shapiro-Wilk test and the Durbin-Watson test. The Shapiro-Wilk test was performed to see whether the values of the standardized residuals followed a normal distribution. The \(p\)-values above 0.050 in the two regressions (0.851 for the first and 0.721 for the second) confirmed that the residuals were normally distributed [55]. The Durbin-Watson test served to verify whether the assumption of independence of residuals was met. The values of this indicator between 1 and 3 in both regressions (1.847 for the first and 1.425 for the second) verified that the requirement of independence of residual was satisfied [56].
