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

We have learned about systems variables which are the way the police and state officials do things that they have control over such as lineups‚ procedures‚ interrogation. Estimator variables are things that are outside of our control such as age‚ race‚ distance‚ lighting which the system has no control over. By having effective systems variables such as lineups and interrogation process many witnesses can play a big role in
