Pareto Analysis and Graphical Summary of Historical Data helped to find out a baseline of 64.88 % casts having silicon in hot metal more than 0.7% and an entitlement of 33% casts on daily average data base. A target of reduction of percentage casts having silicon more than 0.7% from 64.88% to 40 % had been taken up. Through DMAIC process initially 53 inputs were identified in Detailed Map‚ which was scaled down to 5 critical inputs after C&E Matrix and FMEA. Regression Analysis was done on

LIMITATIONS OF BIVARIATE REGRESSION. Often simplistic (multiple relationships usually exist. Biased estimates‚ even if relevant predictors are omitted. WHY IS ESTIMATING A MULTIPLE REGRESSION MODEL JUST AS EASY AS BIVARIATE REGRESSION? Because a computer does all the calculations so there is no extra computational burden.

Assignment #2 EC1204 Economic Data Collection and Analysis Student No. 110393693 Part 1: Question 2 From analysing the Data on the Scatter Plot the relationship between the GDP and the Population of Great Britain from 1999-2009 appears to be a moderate positive correlation relationship. Both variables are increasing at a similar rate and following a similar pattern which would indicate this relationship. This relationship would tend to be a positive one as more people are available to the

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

Part II Final Project assignment. When constructing a multiple regression model‚ we must ask the question “Does a linear relationship exist between the dependent variable and the independent variables. Based on the multiple regression model of the Virginia hospitals data‚ all of the independent variables are not significant predictors of the dependent variable. This is evidenced by the varying p-values shown in the regression analysis. The null hypothesis for each independent variable states that

dissertations. This write-up provides a general overview of the most common data assumptions which the researcher will encounter in statistical research. SOUND MEASUREMENT Descriptive Statistics All forms of statistical analysis assume sound measurement‚ relatively free of coding errors. It is good practice to run descriptive statistics on one’s data so that one is confident that data are generally as expected in terms of means and standard deviations‚ and there are no out-of-bounds

Multiple Regression Project The is the only deliverable in Week Four. It is the case study titled “Locating New Pam and Susan’s Stores‚” described at the end of Chapter 12 of your textbook. The case involves the decision to locate a new store at one of two candidate sites. The decision will be based on estimates of sales potential‚ and for this purpose‚ you will need to develop a multiple regression model to predict sales. Specific case questions are given in the textbook‚ and the necessary data
