Dependent variables are those which have one-way arrows pointing to them and independent variables are those which do not. Dependent variables have residuals (are not perfectly related to the other variables in the model) indicated by e’s (errors) pointing to …

-A factorial analysis allows the researcher to determine the effect of the independent variable and the control variable on the dependent variable both separately and in combination. -It permits determination of whether there is interaction between the independent variable and the control variable such that the independent variable operates ...

A . main effect. is the effect of a single independent variable on a dependent variable – ignoring all other independent variables. For example, imagine a study that investigated the effectiveness of dieting and exercise for weight loss.

Multiple linear regression analysis is used to examine the relationship between two or more independent variables and one dependent variable. The independent variables can be measured at any level (i.e., nominal, ordinal, interval, or ratio). However, nominal or ordinal-level IVs that have more than two values or categories (e.g., race) must be ...

And we assume that the dependent variable can be expressed as a linear function of some independent variables, not just put X here. It is that independent variable. So ordinarily least squares Y are a dependent variable is a function of some fixture of alpha that we estimate plus beta, another term that we estimate, a parameter of the estimate.

GLM does not assume constant variance; in fact, it assumes that there is some sort of function that explains the relationship between the variance and the mean, that the variance in Y, in this case cost, is somehow conditional on the independent variables. There’s a bunch of possible variance functions.

Where Y is the dependent variable, measured in units of the dependent variable, X is the independent variable, measured in units of the independent variable, and a and b are constants defining the nature of the relationship between the variables X and Y. The “a” or …
