Suppose the systolic blood pressure for healthy children is modeled by p = Bo + B1 In w where is blood pressure in millimeters of mercury and w is weight in pounds. Find the least squares solution to this model using the following data and the associated Normal Equations: W 44 61 81 113 131 In w 3.78 4.11 4.39 4.73 4.88 91 98 103 110 112 Use your results to predict the blood pressure for a 100-pound healthy child. NOTE: Keep all computations accurate (rounded) to the thousandths place until the end... rounding early will cause significantly different results!
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
