1 Brush salmon fillets on both sides with 1/4 cup butter, and sprinkle evenly with the cayenne pepper mixture. 2  Drizzle one side of each fillet with 1/2 remaining butter. 3  In a large, heavy skillet over high heat, cook salmon, butter side down, until blackened, 2 to 5 minutes.

The intercept (often labeled the constant) is the expected mean value of Y when all X=0. Start with a regression equation with one predictor, X. If X sometimes = 0, the intercept is simply the expected mean value of Y at that value. If X never = 0, then the intercept has no intrinsic meaning. In scientific research, the purpose of a regression model is to understand the relationship between predictors and the response. If so, and if X never = 0, there is no interest in the intercept.
In this case, the intercept is the unweighted mean of the individual group means. The unstandardized regression coefficient represents the difference between the unweighted mean of the means of one group (A) and the unweighted mean of another group (B), where A and B are two sets of groups in the contrast.
