analysis of the data includes regression analysis. Data The collection agency supplied a sample of 96 randomly selected customer bills. These bills demonstrate the following information: * One dependent variable (y), which is the number of days to collect the payment * Two independent variables (x1 & x2), which are the amount of the overdue bills and the specific type of customer accounts Results * The model depicts an average time of 50 days late for the bill * The average amount

Questions 10.1. What is a confounding variable, and why do confounding variables create problems in research studies? An extraneous variable is a variable that MAY compete with the independent variable in explaining the outcome of a study. A confounding variable (also called a third variable) is a variable that DOES cause a problem because it is empirically related to both the independent and dependent variable. A confounding variable is a type of extraneous variable (it’s the type that we know is a

4278 X = The independent variable which is Benefits’ Y = The corresponding dependent variable which is Intrinsic’ The slope (m) = 0.1697, and the intercept (b) = 4.4278 Therefore the Correlation Coefficient, r = 0.4061 and the Coefficient Determination, [pic] = 0.1649 [pic]. Benefits and Extrinsic Job Satisfaction Test #2: Regression Analysis-Benefits & Extrinsic: The equation for the Least Square Regression is y = -0.1622x + 6.1573 X represents the independent variable ‘benefits’

Applied Econometrics BE5103 Tutorial 1 Q1 a) In the simple OLS regression estimation it is not possible that all actual independent Yi values lie above the estimated regression line. This is because OLS minimizes SUM ê2 , the residual , ê, is the difference between the actual Yi and the predicted Yi and has zero mean. In other words, OLS calculates the slope coefficient so that the difference between the predicted Yi and actual Yi is minimized. The OLS estimates of the βs: Are unbiased – the

(ACE) algorithm of Breiman and Friedman (1985) for estimating the transformations of a response and a set of predictor variables in multiple regression that produce the maximum linear effect between the (transformed) independent variables and the (transformed) response variable. These transformations can give the data analyst insight into the relationships between these variables so that relationship between them can be best described and non-linear relationships can be uncovered. The power and usefulness

1) Hypothesis: To statistically evaluate questions, we need to put forward a hypothesis, which is an unproven testable proposition or supposition that tentatively explains certain facts or phenomena. It is a statement of assumptions we have about the nature of populations or relationships. So, Hypothesis is an educated guess based on the material that one has read. Hypothesis testing involves the careful construction of two statements: the null hypothesis and the alternative hypothesis. To statistically

called, variables because they can vary in quantifiable ways. Age, educations, weight, grade point average, socioeconomic status, income, IQ scores, anything that can be measured is a variable. Scatterplots and correlation coefficients allow us to make predictions from a person’s score on one characteristic to another characteristic. They do not, however, provide any way to say what causes the person’s score on either characteristic. A positive correlation means that high values of one variable are
