Regression analysis

econometric variables. It is his intention to base his forecasting decisions and projections for the upcoming year on results derived from analysis surrounding this theory. An initial analysis was conducted on historic sales data using excel to calculate descriptive statistics. From there several other forecasting models were introduced: Regression with seasons, Regression with factors, Holt Winters Additive and Multiplicative were also used in predicting quarterly sales for 2008. Based on the outcomes

Statistical Analysis of Campus Crime Reported by Xing Huang Abstract The report sets out two hypothesizes to examine whether the factors—acceptance rate, campus size, private and number of admin staff—have a influence on the number of both 2010 and 2011 burglaries. The purpose of this report is to provide evidence for city managers to deal with the campus crime. The analysis indicates that city managers should carry out a more effective program for private schools to protect students from campus

MATH 533(Applied Managerial Statistics) Project AJ Davis Department Stores; Part C: Regression and Correlation Analysis Using MINITAB perform the regression and correlation analysis for the data on CREDIT BALANCE (Y) and SIZE (X) by answering the following. 1. Generate a scatterplot for CREDIT BALANCE vs. SIZE, including the graph of the "best fit" line. Interpret.

the “Lg10” function under the “Transform/Compute Variable” pull down menu feature of IBM’s Statistical Package for Social Sciences (SPSS). Once the variables were transformed, we ran a correlation analysis between the operationalized independent variables, moderating variables, control variables and the dependent variable to check for collinearity and to begin to identify and evaluate non-causal associations and strengths of relationships between variables. We also applied Variance Inflation Factors

project: whether it will be a project that is able to be completed, a project that is worth pursuing, and a project that is economically justified. A reasonable and informed cost estimate can only be reported to a customer after effort estimation analysis has been performed. Formal models, created to improve the accuracy of effort estimation, date back as early as the 1960s when computer software was still in its youth. In recent decades, more flexible alternatives to the hard-and-fast formal models

perform the regression and correlation analysis for the data on CREDIT BALANCE (Y) and SIZE (X) by answering the following. Generate a scatterplot for CREDIT BALANCE vs. SIZE, including the graph of the "best fit" line. Interpret. The scatter plot of Credit balance ($) versus Size show that the slope of the 'best fit' line is upward (positive); this indicates that Credit balance varies directly with Size. As Size increases, Credit Balance also increases vice versa. MINITAB OUTPUT: Regression Analysis:

PURPOSE This report will discuss the simple linear regression model; throughout two variables, the predictor variable (independent) and one response variable (dependent) will be used to explain the models. In so doing, it explains the underlying assumptions when fitting both variables into models and statistical tools. In addition to findings from statistical analyses, this report communicates in clear terms the significance of data on the retention rate (%) and the graduation rate (%) for the sample

Size of the car being tested. To do this, a multiple regression analysis was run using Cost/Mile as the dependent variable, and the ‘dummy’ variables Family-Sedan and Upscale-Sedan as independent variables. In examining the results, the first thing we notice is the “R Square” value is 0.7471. This represents the multiple coefficient of determination (r2), which is basically a measure of goodness of fit of the equation estimated by the analysis. This means that the size of the car roughly accounts
