  With a p-value of 0.0, there is very strong evidence to suggest that the simple linear regression model is useful for BAC. Interpreting r2. The r2 value listed on the output is 80%, which is implies that about 80% of the sample variation in blood alcohol level (y) is explained by the number of beers a student drinks (x) in a straight-line model.

  Hypothesized Regression Equation/Model and the Estimating Equation. When we follow the steps in regression (coming up shortly) we come up with two forms of our regression line or model. The first is a hypothesized model (following the general format of steps to research design) From a previous example, on Effort and Performance in 520, we had ...

  Model Assumptions. The Simple Linear Regression model, Y = X + , makes two different types of assumptions. The first of these, mentioned previously, postulates that Y and X are linearly related, i.e., that the line . Y = + X appropriately models the relationship between the …

  A simple regression, which implies a single independent variable, can accommodate most any functional relation between the left-hand side [LHS] (i.e., dependent) variable and right-hand side [RHS] (i.e., independent) variable.In general, it is easier to think about the relation between the variables as either linear or non-linear (i.e., concave, convex or some arbitrary polynomial).

  An alternative to using Fit Y by X to perform simple linear regression, is to use the Fit Model option from the Analyze menu. The advantages of this approach are two-fold: 1) You have access to more detailed results from your regression and have enhanced features for estimation/prediction of Y.
