Plots Linear regression is a crucial tool in identifying and defining key elements influencing data. Essentially‚ the researcher is using past data to predict future direction. Regression allows you to dissect and further investigate how certain variables affect your potential output. Once data has been received this information can be used to help predict future results. Regression is a form of forecasting that determines the value of an element on a particular situation. Linear regression

TOPIC – LINEAR PROGRAMMING Linear Programming is a mathematical procedure for determining optimal allocation of scarce resources. Requirements of Linear Programming • all problems seek to maximize or minimize some quantity • The presence of restrictions or constraints • There must be alternative courses of action • The objective and constraints in linear programming must be expressed in terms of linear equations or inequalities Objective

DUE: OCTOBER 16‚ 2014 CASE PROBLEM The Southern Textile Mill produces 5 different fabrics. Each fabric can be woven on one or more of the mill’s 38 looms. The sales department’s forecast of demand for the next month is shown in Table 1 along with data on the selling price per yard‚ variable cost per yard‚ and purchase price per yard. The mill operates 24 hours a day and is scheduled for 30 days during the coming month. Fabric Demand Selling Price Variable Cost Purchase Price (yards)

Linear Programming History of linear programming goes back as far as 1940s. Main motivation for the need of linear programming goes back to the war time when they needed ways to solve many complex planning problems. The simplex method which is used to solve linear programming was developed by George B. Dantzig‚ in 1947. Dantzig‚ was one in who did a lot of work on linear programming‚ he was reconzied by several honours. Dantzig’s discovery was through his personal contribution‚ during WWII when Dantzig

Linear Model[edit] It is a one way model to communicate with others. It consists of the sender encoding a message and channeling it to the receiver in the presence of noise. In this model there is no feedback which may allow for a continuous exchange of information. This form of communication is a one-way form of communication that does not involve any feedback or response‚ and noise. (F.N.S. Palma‚ 1993‚ Shannon and Weaver[edit] The new model was designed to mirror the functioning of radio and telephone
