EFFECT OF WORKING CAPITAL MANAGEMENT ON PROFITABILITY OF FIRMS IN MALAYSIA ( M. A., Zariyawati a, M. N., Annuar b and A.S., Abdul Rahim c a ,b & c Univeristi Putra Malaysia, Malaysia. ABSTRACT Working capital management is important part in firm financial management decision. An optimal working capital management is expected to contribute positively to the creation of firm value. To reach optimal working capital management firm manager should control the trade off between profitability and

linear regression allows you to predict scores on one variable to the scores on a second variable. It uses one independent variable to describe the relation of the independent and dependant variable as a line. Multiple regressions are learning about the independent and dependent variables relationship between each other. It enables you to predict the value that is unknown from two or more variables. It assists with the prediction of the value of Y. Non-linear regression is an analysis where

ANALYTICS Data Mining is the computerized acknowledgment of diverse patterns in extensive data sets that are past analysis. It utilizes diverse mathematic algorithms to locate the right information as well as foresee the probability of future events. Some key properties that I learned in this topic are: • discovery of useful patterns • predictions of their future outcomes • analysis on larger datasets • useful data from them With increasing data the storage of the data must also be increased

5. Results 5.1 Decision Trees Evaluating the Model In this case the model results include: Tables that provide information about the model. Tree diagram. Charts that provide an indication of model performance. Model prediction variables added to the active dataset. The tree diagram is a graphic representation of the tree model. This tree diagram shows that: Using the CHAID method, thal factor is the best predictor of heart disease. For the value 6 and 7 for thal, the next best predictor

4.4.3 Regression Analysis In this study, a multiple regression analysis was applied to test the influence among predictor variables. The research used statistical package for social sciences (SPSS V 20) to code, enter and compute the measurements of the multiple regressions.

CASE 49: PROPERTY CRIMES I. Executive summary The focus of this study is the examination of the data provided by U.S government agencies. Our analysis revealed that of the eight possible contributing factors, only three variables (namely, urbanization rate, high school dropout rate, and population density) affected property crime rates. Our data analysis model accounted for approximately 66% of the factors contributing to property crimes. The model is generally considered to be statistically strong

household individuals, handling of the economy index and lived poverty in Africa. For the analysis of the multidimensional problem of lived poverty in Africa, a multiple regression model was used to answer the research question. Multiple regression models allow the examination of how two or more independent variables effect a dependent variable (Frankfort-Nachmias and Leon-Guerrero 2015). Multiple regression is used to predict a continuous dependent variable base on multiple independent variables;

Purbasari (2006) on Indonesia, Johnson and Mitton (2003) on Malaysia, Agrawal and Knoeber (2001) on US and Sapienza (2004) on Italy. Faccio (2006) and Faccio, Masulis and McConnell (2006) however, used an international sample and a cross country analysis approach to investigate the phenomenon of political connectivity across the globe. In this paper, the authors identify the gap in the literature to argue the

of the methods used are given below. Ordinary Least Squares Method After collecting and cleaning the data, the first model was built using all the regressors under consideration. A thorough analysis of this full model, including residual analysis and multicollinearity check was done. The best subset regression was also tried. The normal probability
