40 JOURNAL FOR ECONOMIC EDUCATORS‚ 10(1)‚ SUMMER 2010 UNDERGRADUATE RESEARCH Public Transportation Ridership Levels Christopher R. Swimmer and Christopher C. Klein 1 Abstract This article uses linear regression analysis to examine the determinants of public transportation ridership in over 100 U. S. cities in 2007. The primary determinant of ridership appears to be availability of public transportation service. In fact‚ the relationship is nearly one to one: a 1% increase in availability is

Jackson‚ MD MPH Kent Dezee‚ MD MPH Kevin Douglas‚ MD William Shimeall‚ MD MPH Traditional multivariate modeling (linear regression‚ ANOVA‚ Poisson regression‚ logistic regression‚ proportional hazard modeling) is useful for examining direct relationships between independent and dependent variables. All share a common format: Dependent Variable = Independent variable1 + Independent Variable2 + Independent

A sodium hypochlorite (NaOCl) solution was also prepared by mixing 8.00 mL of a stock solution with DI water to obtain 50 mL. The concentration of the NaOCl solution was also determined using the following equation: M1V1 = M2V2 (Eq. 2) The second part of the experiment involved mixing different proportions of both the NaOCl solution and blue food coloring solution‚ and this was performed in order to determine the proportion of each which was necessary to

the demand for the product. The consultant should also describe the methodology of a multiple linear regression and its purpose in estimating a demand function. The consultant should then run a multiple linear regression in linear and multiplicative forms based on the data provided by the company and report on the estimated result. They will have to evaluate the estimated demand equations both in linear and multiplicative forms‚ select the one‚ which can best describe the consumption. The consultant

a decision for Linear Technology on dividend policy. The report analyzed the impact of changing future dividend policy on the value of the company‚ based on its historical performance‚ financial history and market trends. Linear Technology is a large-scale company which focus on the analog segments within semiconductor industry. It went public in 1986 and announced its dividend policy on 1992. Nowadays‚ under the market environment where dividends are unwilling to be paid‚ Linear still insisted

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
