This pattern is used for rear-wheel drive or 4-wheel drive vehicles. Natural selection is the mechanism of evolution which favors organisms that are better adapted to their environments. Under directional selection, the advantageous allele increases as a consequence of differences in survival and reproduction among different phenotypes. an opportunity for deciding between two or more courses or propositions. In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships between a dependent variable (often called the 'outcome' or 'response' variable, or a 'label' in machine learning parlance) and one or more independent variables (often called 'predictors', 'covariates', 'explanatory variables' or 'features').
