...?Quantitative Analysis Discuss the requirements of a **linear** **programming** (LP) model. Provide an example of an LP model and define each variable used. What are the key steps that need to be considered when formulating an LP problem? A **linear** **programming** model tends to consider **linear** inequalities in a number of variables that can be solved together in order to optimize the solution for any particular variable. A typical LP problem would be to optimize which is subject to the following conditions: In these circumstances the variables x, y and z could represent material costs and labor costs respectively while z represents optimal cost. In order to set up...

...? RESPONSE FORMAT/ **LINEAR** **REGRESSION** Introduction At no given point whatsoever should a response format should be confused with a scale whatever the situation. With the misconceptions, misunderstandings, factual and empirical errors surrounding a given range of response formats it is important to address the challenges above to aid clarity in the operations. The two major response formats that we want to exclusively dissect are the Likert response format and the open-ended questions or interviews (Fisher, Weiss & Dawis 1968). Likert Scale The response format is of much interest because it is what was used to create 25 test items for an assignment a week ago. It was appropriate because it is the right...

...in the **regression** model, the least squares criterion has various statistical properties that are desirable, particularly, the estimates are maximum possibly if the residuals ei are normally distributed. Therefore if the **regression** equation is estimated then we arrive at the following. 23.083x35 +711.651 = 1519.556 10) When the **regression** equation is used, the predicted monthly family income for women working 20 hours per week is By considering the equation below as well The **regression** equation is estimated then we arrive at the following. Where ?1 is the slope of the line and ?0 the intercept. It is assumed that the error terms ei have a mean value of 0. 23.083x20...

..."**Programming**, both **linear** and non-**linear**, is entirely a mathematical technique. Its economic meaning is therefore nil". (W.Baumol). Introduction: Most of the **decision** models are formulated in terms of mathematical symbols and relations. Mathematics gives precision which is important in **decisions**. **Decisions** have to be precise and sharp. To the extent that the economic **decisions** are measurable and quantifiable, the use of mathematics is acceptable. Symbols and numbers alone do not suffice; additionally, the logic of reasoning behind those numbers and symbols is also required. Scientific **decisions** arrived through the use of mathematical tools and statistical techniques should have an intuitive appeal and logical support, otherwise... , the...

...of independence. This implies that the production of both products is independent of each other and so is their impact on the number of machining or assembly hours. Therefore, the two effects can be added to each other.
The second assumption is the assumption of **linearity**. In other words it is assumed that a **linear** relation exists between the number of products and machining or assembly hours. This assumption makes possible the use of **linear** **programming** model for the given problem.
4. Optimal Solution
The optimal solution can be obtained by solving the above model through Excel solver as shown in Figure 4.1 (Taha, 2009). In the beginning, the number of products of each...

...**Linear** **Regression** and **Regression** Analysis **Regression** is a technique in statistics that enables estimation of the relation existing among variables. The technique seeks to estimate the strength of the relationship between one variable with another or a set of variables. However, when applying this technique, the statistician makes assumptions with regard to the variables and their relationship. **Regression** is based on the assumptions that there exists a **linear** relationship between the involved variables and that they have an additive relationship. There are many **regression** techniques one of them being...

...**Multiple** **Linear** **Regressions** al Affiliation: **Multiple** **Linear** **Regressions** Types of F test The two types of F test are Type and Type 3. Type I is called the sequential sum of squares. It is used for testing the main effect of the first factor followed by the second factor and then the interaction effect. Type 3 test identifies the presence of main effects followed by the interaction of these effects.

...**Linear** **programming**
1. A
The variables in a **linear** **program** are a set of quantities that need to be determined in order to solve the problem; i.e., the problem is solved when the best values of the variables have been identified. The variables are sometimes called **decision** variables because the problem is to decide what value each variable should take. Typically, the variables represent the amount of a resource to use or the level of some activity.
1. B
**Linear** **programming** is a response to situations that require the maximization or minimization of certain functions which are subject to limitations. These limitations are...
