PPT-Comparing Regression Lines

From Independent Samples The Design You have two or more groups One or more continuous predictors C And one continuous outcome variable Y You want to know if Y a b 1 C 1 . Di64256erentiating 8706S 8706f Setting the partial derivatives to 0 produces estimating equations for the regression coe64259cients Because these equations are in general nonlinear they require solution by numerical optimization As in a linear model isavectorofparameterstobeestimatedand x isavectorofpredictors forthe thof observationstheerrors areassumedtobenormallyandindependentlydistributedwith mean 0 and constant variance The function relating the average value of the response to the pred Linear Function. Y = a + bX. Fixed and Random Variables. A FIXED variable is one for which you have every possible value of interest in your sample.. Example: Subject sex, female or male.. A RANDOM variable is one where the sample values are randomly obtained from the population of values.. Tom Hopson. Luca . Delle. . Monache. , . Yubao. Liu, Gregory Roux, . Wanli.

Many applications of statistical analysis involves a continuous variable as dependent variable (DV) but both continuous and categorical variables as independent variables (IV). . Relationship between DV and continuous IVs is linear and the slope remains the same in different groups: ANCOVA.. R. ational Numbers. TeacherTwins©2014. 2). Warm Up.

Recall: Prokaryotes are represented by 2 domains- Bacteria, Archaea. Therefore we can compare and contrast Bacteria and Archaea by looking at the following:. Type of cell ( eukaryote? Prokaryote? ). : A British biometrician, Sir Francis Galton, defined regression as ‘stepping back towards the average’. He found that the offspring of abnormally tall or short parents tends to regress or step back to average.. Fun facts about the regression line. Equation of regression line: . If we convert our X and Y scores to . z. x. and . z. y. , the regression line through the z-scores is:. Because the means of the z-scores are zero and the standard deviations are 1.. .
