| scale_01 | Scale a vector into the 0-1 scale |
| test_coef_equality | testing equality of two coefficients (difference between coefficients of regressors), a Wald test note: if v is not alternatively specified, use car::linearHypothesis(lm_model, "X1 = X2") |
| test_tilted_slopes | significance of regression slope (the marginal effect) under moderation testing restriction: the sig. of beta_x under the moderation of z1, with or without additional interaction terms (z2, z3, etc.) |
| to_long_tab | Convert the regression result to the long format: the standard errors are in parentheses and beneath the betas |
