forecasting decisions with fewer errors. In this paper‚ demand estimation will be done through a regression analysis. This analysis will examine the elements that management should look at when determining demand for a product such as: price‚ competitor’s price‚ customer income‚ advertising and the cost of microwave ovens. The main objective of this paper will be to: estimate the demand function using regression analysis‚ find elasticities of demand with respect to various variables and make forecasting

intervals and prediction intervals from simple linear regression The managers of an outdoor coffee stand in Coast City are examining the relationship between coffee sales and daily temperature. They have bivariate data detailing the stand ’s coffee sales (denoted by [pic]‚ in dollars) and the maximum temperature (denoted by [pic]‚ in degrees Fahrenheit) for each of [pic] randomly selected days during the past year. The least-squares regression equation computed from their data is [pic].

The logistic regression analysis in this dissertation was used to predict the outcome of the acceptance of traffic-free zone (value of 1) based on various attributes. To analyse the variable which is categorical such as trip purpose‚ one category within each independent variable was assigned as reference category so regression coefficient could be given for each other category in the independent
