Given the data‚ please construct (a) a multiple linear regression equation and (b) a log-linear (exponential) regression equation for demand by MS Excel. (20%) 2. Given the MS Excel output in question 1‚ please compare the two regression equations’ coefficient of determination (R-square)‚ F-test and t-test. Which equation is a good (better) fit? Which equation shows the stronger overall significance to predict the future demand? Which equation will you choose for a better demand estimation? Explain

Dividend Policy at Linear Technology Of the 16 companies on the SOX index‚ six paid dividends and Linear Technology is one of them started at the second quarter in 1993 which is 5.3 million in total. However‚ in the case‚ according to Coghlan‚ “The quarterly dividend was initially set at $0.05 per share. This amounted to $8.3 million‚ or 15% of FY 1994 earnings.” And their most recent dividend in 2002(cause in the exhibit2‚ there’s only threes quarter’s data in 2003‚ so that’s why I choose 2002

Forecasting Models: Associative and Time Series Forecasting involves using past data to generate a number‚ set of numbers‚ or scenario that corresponds to a future occurrence. It is absolutely essential to short-range and long-range planning. Time Series and Associative models are both quantitative forecast techniques are more objective than qualitative techniques such as the Delphi Technique and market research. Time Series Models Based on the assumption that history will repeat itself‚

Explain the geometric sense of a linear system in two variables. Describe the possible cases. 2. Geometric sense of a linear system of inequalities in two variables. 3. How do the special products help us factor polynomials? Give examples. 1. Linear system in two variables can be written in the form: a x + b y = p c x + d y = q - If a‚ b‚ p – and – c‚ d‚ q are real numbers ( if a‚ b and c‚ d are not both equal to 0) - x and y are called two variables. 2.
