Predictive methods are grouped as ____ techniques when the dependent variable is binary or discrete - classification Predictive methods are grouped as ____ techniques when the dependent variable is continuous. - predictive The use of previously observed events and the description of the target data in terms of a set of ____. - explanatory variables ____ common way of estimating the relationship between one or more input variables and a continuous target variable - linear regression if us...

Bivariate Statistics - Use of Contingency Table correct answersUsed to detect incompatibilities between variables, links between the dependent ('target') variable and the independent variables and their interactions, in order to eliminate the variables having no effect on the dependent variable; links between the independent variables, which must be avoided in some methods, such as linear and logistic regression. Detection of Rare Variables correct answersRare values can create bias in fac...
