- Estimate sensitivity, specificity, positive predictive value, negative predictive value and prevalence from data in the 2 x 2 table for an infectious disease and its diagnostic test.I have collected real data on the sale of a microwavable cup of soup across 20 different cities for the same time period (a month). The variables in the dataset are: Quantity sold in the city for that month: Measured in thousands of units Price: measured in dollars Average Income in the city: Measured in thousands of dollars Ads: Average number of ads run in stores for that city during that month. Price of a substitute product: measured in dollars Population of the city: measured in thousands of people The dataset is on Canvas and, using Excel or any other statistical software, please answer the following questions: 1. Describe the patterns in quantity sold and own and rival prices during this time period using basic descriptive statistics. Graphs are welcome as well. 2. Take the logs of the variables, and estimate the demand function. a. Interpret the R-square. b. Interpret the coefficients for logP and logPsub c.

- How is multiple linear regression different from simple linear regression? Multiple regression involves 2 or more dependent variables. Multiple regression involves 2 or more independent variables. Multiple linear regression involves a numeric independent variable and a categorical DV. Multiple linear regression has more levels.I did questions that I already understood I just need help with question b and question CFit a linear regression model using the empirical probit as the dependent variable and the log dose level as the independent model – that is, set-up your probit model. What would be the visual Linear regression Models of c and d.
- Diabetes Improving control of blood-glucose levels is an important motivation for the use of insulin pumps by diabe- tic patients. However, certain side effects have been reported with pump therapy. Table 2 provides data on the occurrence of diabetic ketoacidosis (DKA) in patients before and after start of pump therapy. Table 2: Occurrence of DKA in patients before and after start of insulin-pump therapy Before pump therapy After pump therapy No DKA DKA No DKA 145 72 DKA 65 28 10. What is the appropriate procedure to test whether the rate of DKA is different before and after start of the pump therapy? 11. Perform the significance test in Problem 10, and report a p-value.3a) Why do we need to collect information and data? -what is quantitative data? -give an example for discreet data -give an example for continuous data
