analysis is performed in which children and adults are considered separately, an effect of sex on weight is seen only in adults, and not in children. Its broad spectrum of uses includes relationship description, estimation, and prognostication. Measures of association provide an initial impression of the extent of statistical dependence between variables. In the multivariable regression model, the dependent variable is described as a linear function of the independent variables Xi, as follows: Y a b1 X1 b2 X2. Each of the coefficients bi reflects the effect of the corresponding individual independent variable Xi on Y, where the potential influences of the remaining independent variables on Xi have been taken into account,.e., eliminated by an additional computation. It is better practice, however, to give the corrected coefficient of determination, as discussed in Box. The methods of regression analysis are comprehensively discussed in many standard textbooks ( 1 3 ).
A linear regression is an appropriate analysis when the goal of research.

The coefficient of determination, r2, is a measure of how well the regression model describes the observed data ( Box 2 ). Moreover, if too many irrelevant variables are included in the model, overadjustment is likely to be the result: that is, some of the irrelevant independent variables will be found to have an apparent effect, purely by chance. One can also compute the 95 confidence interval for the regression coefficient ( 4 ). Backward selection Backward selection, on the other hand, starts with a model that contains all potentially relevant independent variables. The remaining.5 is due to individual variation and might be explained by other factors that were not taken what is the solution for air pollution essays into account in the analysis, such as eating habits, exercise, sex, or age. Moreover, selection effects can be expected in such cases. If this happens, real relationships can be overlooked, and the study findings may not be generally applicable.
