For the interaction models, in order to find a main effects model, age group was used as a main effect and steps 1 through 4 were repeated.
Variables in the model: age group engine capacity warning police controls penalty for speeding others break speed limits expectation of speed enforcement.
Variables in the model: age group wished higher limits warning police controls penalty for speeding others break speed limits expectation of speed enforcement.
Based on this model, age group means for absolute values were estimated and mean age group ratios were estimated together with two-sided 95%% confidence intervals (CIs).
For the 1999 2000 survey period, in the final multivariate model, age group and time of sample collection were the only significant variables in addition to log-transformed creatinine.
In our multiple linear regression model, age, group, education, average waist girth, functional comorbidity index, general mobility and global cognition were statistically controlled by forcing these six variables into the regression model first (Model 1).
* P < 0.05, ** P < 0.01, *** P < 0.001. 1 β is negative for CBCL in this model (age group 11-17 years); in all the other regression models, the ASEBA predictors had positive β values.
In the final model, age group (in categories of 10 years), the extent of contact between hunters and wild boars and the hunting ground plus the according interaction term were included as independent variables.
To assess the associations between the characteristics and nonparticipation, we performed multiple logistic regression analyses assessing following covariates simultaneously in the model: age group, number of comorbidities, marital status, living status, travel distance, BMI, previous chemotherapy, and fatigue.
In Table 2, the characteristics of motorcycle occupants and crashes were compared among three motorcycle model age groups.
Additional factors were gender and age factored initially into eight groups (<1, 1 4, 5 9, 10 14, 15 24, 25 39, 40 59 and 60+ years of age); if age was overall significant in the minimum adequate model, age groups were combined when not significantly different as ascertained by t-test and the final statistical model applied.
