independent variables • Regression equations are computed on the basis of a regression line: the geometric line representing, with the least amount of discrepancy, the actual location of points in a scattergram. • Types of regression analysis include linear regression analysis, multiple regression analysis, partial regression analysis, and curvilinear regression analysis. Inferential Statistics • Inferential statistics are used to estimate the generalizability of findings arrived at through the

A statistical analysis of consumer confidence and unemployment numbers An analysis in R Clemens Timmermans (s0867144) 5/1/2009 INTRODUCTION Statistics matters. CBS.nl presents Dutch facts every month and to make sense of this data statistical analysis is a must. Without this kind of analysis these numbers are just numbers without meaning. For this paper the input came from CBS.nl as well, and here I will outline what the predictive capability of the consumer confidence indicator is for unemployment

Linear Regression I would like to know if people who enjoy thrill seeking have tattoos. I believe thrill seeking and tattoos go hand in hand. Most people I know are adventurous, risk takers, and daredevils and all of them have tattoos. I have a strong feeling that the correlation between the two will have a strong positive relationship. X= Tattoos Y= Thrill Seeking The scatter plot shows an extremely rough linear pattern but there is an upward sloping. Line of best fit: y = 0.9148x +25.505

Adjusted R Squared to compare the Linear or Semilog Regression. R^2 is a statistic that will give some information about the goodness of fit of a model. In regression, the Adjusted R^2 coefficient of determination is a statistical measure of how well the regression line approximates the real data points. An R2 of 1 indicates that the regression line perfectly fits the data. Brand1: Linear Regression R^2 | 0.594 | SemiLog Regression R^2 | 0.563 | We use the Linear Regression Model since R-squared

Shown below is Minitab output for correlation and regression analysis for the education and sick day data. The correlation between hours of education and number of sick days is an electively strong negative correlation. This indicates that the more hours of education received the fewer the sick days. There may be several reasons for this. One explanation may be that as workers participate

health, observed from symptoms and diseases. Questionnaires were used for data collection and sent to the sample through emails and in person, 891 in total. There were 109 completed questionnaires. Data were analyzed by using descriptive analysis, linear regression and logistic regression analyses. This study found that neck ache and shoulder pain, and stress were most found in the sample of auditors. The independent factors statistically associated with symptoms and diseases are work hours and
