between Marital Satisfaction and Father Involvement
Finally, we point out that curvilinearity
is a potential cause of spurious moderator effects (see Lubinski & Humphreys, 1990; MacCallum & Mar, 1995).
And then that spins off, as you might expect, into subtexts that are really rather specific--natural light, water, the presence of water, curvilinearity
, organic forms, because most of our design aesthetics--not always--but most our design aesthetics frequently come from nature.
The steep curvilinearity
of outcomes at the bottom of the grade
If the quadratic term produced a significant increase in fit, we considered the relationship to have significant curvilinearity
(Sokal & Rohlf 1995, p.
was tested by including drinking frequency squared to a bivariate logistic regression of the LSA 13-14-drinking frequency relationship.
These comments suggest that this hypothesis of curvilinearity
is one worthy of investigation and could help to explain why some earlier empirical work has failed to find a significant relationship between adherence and severity of illness (for example, Eldred et al.
First, however, signs of non-normality, curvilinearity
, non-constant error variance, and outliers were investigated.
Every one of the five continuous variables in the 11-term full models exhibited significant and meaningful curvilinearity
, and categorical terms with multiple levels, such as education, exhibited nonlinear step patterns suggestive of curves.
These folds have curvilinear hinge-lines that show an increase in curvilinearity
toward the Fredericton Fault, coincident with a tightening of the interlimb angle.
Product terms (for example, the product of two or more variables) are used to test interactions, powered terms (for example, the square or cube of an independent variable) are used to test curvilinearity
, and the product or powered terms are entered hierarchically in the regression equation (Long, 1997).
When this dimension of opportunities is analysed as a structural feature of the political system, that is, as a prevailing pattern of the state's openness to social movements (for example, in Kriesi, 1995), the curvilinearity
thesis is not relevant because such studies usually focus on cross-national variation in access, rather than on changes in access or mobilization over time.
