DATA SET 1 Soft Drink Demand Estimation Demand can be estimated with experimental data‚ time series data or cross section data. Sara Lee Corporation generates experimental data in test stores where the effect of an NFL-licensed Carolina Panthers logo on Champion sweatshirt sales can be carefully monitored. Demand forecasts usually rely on time series data. In contrast‚ cross-section data appear in Table 1. Soft drink consumption in cans per year is related to six pack price‚ income per capita

research provides statistical analysis for gross monthly sales in 60 stores using five key measures within a 10km vicinity: number of competitors‚ population in ‘000’s‚ average population income‚ average number of cars owned by households‚ and median age of dwellings. These quantitative variables are the key determinants‚ which will provide substance for descriptive statistics and the multiple linear regression model. This research reports mainly on statistical analysis‚ providing a direct interpretation

Demand Estimation by Regression Method – Some Statistical Concepts for application ( All the formulae marked in red for remembering. The rest is for your concept) In case of demand estimation working with data on sales and prices for a period of say 10 years may lead to the problem of identification. In such a case the different variables that may have changed over time other than price‚ may have an impact on demand more rather than price. In order to void this problem of identification what
