five years on a large sample of households from the 27th round (October 1972 – September 1973). For this project Data from the 63rd Round of the National Sample Survey was used as a sample for analysis. The regression analysis was carried out using Linear‚ Working-Lesser and Double Log Models. The income elasticity was calculated in each case which confirmed the fact that food is a necessity good. Qualitative factors such as seasonality‚ occupation and social group were also incorporated into the

changes in advertising‚ promotion or competition. For this problem we look to try and gather an estimate of what the best forecasting method will be for the demand of services A‚ B‚ and C. The methods of analysis used to attain the figures include; linear regression‚ regression model‚ and forecast error analysis. Plan the Treatment: In order to apply all of the demand forecasting methods properly and acquire the most accurate demand forecast‚ we must do the following… Graph historical demand – define

well as advise his boss on what actions he should take for future production. The method we used to forecast the cell phone orders for the upcoming year is regression analysis; we calculated the linear regression formula from the given data‚ and then applied the formula to the later months. Based on the linear regression equation‚ we anticipate the cell phone industry to continue to grow over the next 12 months‚ but Jordan’s boos should feel free to stray away from actual forecasts for certain months

such that the following two conditions on the random vector [pic]are met: 1. [pic] 2. [pic] the best (minimum variance) linear (linear functions of the [pic]) unbiased estimator of [pic]is given by least squares estimator; that is‚ [pic]is the best linear unbiased estimator (BLUE) of [pic]. Proof: Let [pic]be any [pic]constant matrix and let [pic]; [pic] is a general linear function of [pic]‚ which we shall take as an estimator of [pic].
