Matlab problem - Assignment Example The source code done in matlab contains the models to implement the linear regression functions (Martinez & Martinez 39). In the general equation y = a1x + a0, y is replaced by PV, x by indicator and variable a, by aA. This gives the relationship between the X-axis and the Y-axis (Seber and Lee 63). The three expected output results are scattered dots for data output, one line for regression and standard deviation, one line for standard deviation and the third line for regression line of The first step of developing this system involves the identification of the variables to use in the regression analysis. In this program, the two variables identified are PV and Indication of the solar irradiation. The next step is to develop models for linear regression to determine the relationship between the dependent and the independent variable (Chatterjee and Hadi 57). The third step is to develop a matlab source code file containing the model and able to access the source of data to be analysed. The fourth step is to test the program and remove errors. Since the source code has been developed in matlab software, testing is done by executing the linearregression.m script. If any error is found to prevent the output from appearing, necessary correction is done in the source code (Weisberg 49). The range of the y axis was between 5 and 50 while the x axis was set from 4 to 24. The results were successfully displayed as expected and all the three lines were drawn by the program. The standard deviation for the two variables is 2.34. This indicates that the two variables deviated from the actual mean by a difference of about 2.34. The program was successful in implementing the linear regression between the two variables (Groß 42). It revealed that there is a positive correlation between PV output and the indication of solar irradiation. The scatered dots generate the best fit represented by the regression

Tobacco Shop Franchising Essay Example | Topics and Well Written Essays - 500 words

Tobacco Shop Franchising - Essay Example The reason stems out of the fact that people are often more aware of the product or service offered by a franchise and prefer it to those offered by lesser-known outlets. Another benefit of signing the franchising agreement is that the franchisor has already proved that the operations in this market conducted in this particular manner can be successful. As the Pipe Dreams has been around for eight years and has established a network of franchisees, of which it is known that they have had a high success rate in the past, one can be certain the franchisor has proved that the chosen layout and location of the tobacco shops, the developed pricing policy and assortment of the tobacco goods offered are successful. Moreover, for Ralph Emerson to be able to run his tobacco shop effectively he needs the knowledge and feeling of the goods' peculiarities and the consumer preferences. Probably, in his previous career as a librarian he may have accumulated some knowledge about the tobacco and cigars, most probably through the hobby, but it can not be compared to the expertise of the well-known tobacconist whose ideas have proven their validity during the eight-year period. Therefore, the training and guidance in the assortment choice and the shop decoration is of high importance in this case.
