| Description | Hern√°ndez, L.A. 1999. Logistic Regression for Analysis of Preference. An application for Excel. v. 7. CD-Rom.CIAT, Cali, Colombia. ISBN:958-694-027-6"Preference Ranking" is a tool that explains decisions of acceptance or rejection by identifying the criteria used to select one technology option over another. The preference ranking analysis is based on logistic regression. It facilitates data management and makes it possible to simulate the criteria for acceptance of a technology. The software consists of a matrix in Excel 7.0 for Windows. The user only needs to input field data into an existing file containing the frequency of each technology and its ranking order. When the user has finished this process, the software conducts the analysis automatically. For each technology option, the application produces a ranking order, frequency, probability, and cumulative probability. A graph is generated for each technology option which shows the cumulative probability versus ranking order, and statistical differences (slope m, standard deviation SE, and coefficient of correlation r2). A higher slope with a positive intercept indicates a greater degree of acceptance within the highest ranked options. A higher slope but with a negative intercept indicates rejection, and probability of acceptance for the lowest ranking options. Comparison of acceptance levels across technologies and statistics are also shown. Manual with diskette. The manual contains 22 p. 28 x 21.5 cm. Also available in Spanish. |
