solution to linear programming problems can handle problems that involve any number of decision variables. 3- The value of an objective function decreases as its iso-objective line is moved away from the origin. 4- If a single optimal solution exists to a graphical LP problem‚ it will exist at a corner point. 5- Using the enumeration approach‚ optimality is obtained by evaluating every coordinate (or point) in the feasible solution space. 6- A non-unique solution to a linear program indicates

Be Studied By Residual 1. The regression function is not linear. 2. The error terms do not have constant variance. 3. The error terms are not independent. 4. The model fits all but one or few outliers‚ 5. The error terms are not normally distributed. 6. One or several important predictor(s) have been omitted from the model. Diagnostic For Residuals Six diagnostic plots to judge departure from the simple linear regression model * Plot of residuals against predictor variable

9/12/10 IMP POW Linear Nim In this POW‚ we had to play a game called Linear Nim. In this game‚ we drew 10 lines on a paper‚ and we had to take turns crossing out 1‚ 2‚ or 3 of the marks. The person that crossed out the last mark was the winner. The first task of this POW was to find a winning strategy for this game. After we found this out‚ we were supposed to make variations to the game‚ for instance starting with more or less marks‚ or allowing a player to cross out more or less marks. We were

GROUP 1 ABSTRACT Analysis of Bharti airtel’s subscriber base was done using Time series analytical tools to develop predictive models. Different models linear‚ exponential were developed and December 2009 forecast was made using them. Our research revealed that subscriber growth is non linear thus best explained and predicted by exponential curve such as logistic curve. Introduction Tele-communication has evolved with time and in recent years with the growth in technology

matrix In linear algebra an n-by-n (square) matrix A is called invertible or nonsingular or nondegenerate‚ if there exists an n-by-n matrix B such that where I n denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication. If this is the case‚ then the matrix B is uniquely determined by A and is called the inverse of A‚ denoted by A −1 . It follows from the theory of matrices that if for finite square matrices A and B‚ then also [1] Non-square matrices
