Think about a healthcare scenario where multiple regression might be useful in a healthcare organization. Consider what your dependent and independent variables might be for conducting a multiple regression analysis. Build a small example, and run the regression analysis.
Post a description of the dependent and independent variables you will use for your multiple regression analysis, and then explain your regression model in terms of your dependent and independent variables. Explain how you might measure your variables. Be specific and provide examples.

Example-
How might you measure variables-
Scenario: Effect of certain variables on Blood pressure of 10 individuals
Dependent variable: Blood pressure
Independent variable : Age,Sleeping hours ,weight
Bp is measured using BP machine , weight using weighing message , age and sleeping hours got from the individual
Data :
BP | AGE | WEIGHT |
SLEEPING HOURS |
---|---|---|---|
96 | 25 | 63 | 7 |
132 | 42 | 81 | 8 |
111 | 28 | 53 | 6 |
82 | 66 | 69 | 6.5 |
121 | 89 | 54 | 8.5 |
98 | 52 | 49 | 7 |
107 | 16 | 48 | 8 |
116 | 46 | 98 | 6 |
135 | 76 | 55 | 6.5 |
79 | 34 | 87 | 5.5 |
The regression equation is given as BP = 35.223+0.192(AGE)+0.431(WEIGHT)+8.199(SLEEPING HOURS)
For an individual of age 56 weighing 78 and sleeping for 8 hours ,then the predicted BP is given as 120
