When considering the first variable “Home”‚ I begin by questioning how can the information gathered be classified and broken down. Can it be divided in number order? No. Is one response in some way able to be ranked with value‚ as in this answer is obviously more valuable than this one? No. I believe that Home will be a Nominal Variable. It has multiple categories without natural order or value. When considering the variable “Arrests” I begin by questioning is this information based on words or

Assignment Quantitative Methods Strayer University Step 1 For step‚ one I generated a column of random numbers‚ which will help me to determine the weeks between breakdowns. I used the equation in excel =Rand( ). Next‚ I generated a column to determine the weeks between breakdowns. I used the formula in excel =8*SQRT(r) and used the previous mentioned randomly generated numbers. Once I had the randomly generated weeks‚ I created a column for the cumulative

Explain how the applications of integer programming differ from those of linear programming. Integer programming is concerned with optimization problems in which some of the variables are required to take on discrete values. Rather than allow a variable to assume all real values in a given range‚ only predetermined discrete values within the range are permitted. In most cases‚ these values are the integers‚ giving rise to the name of this class of models. Models with integer variables are very
