Studies have shown that certain features from geography, demography, trade area, and environment can play a vital role in retail site selection, largely due to the impact they asserted on retail performance. Although the relevant features could be elicited by domain experts, determining the optimal feature set can be intractable and labor-intensive exercise. The challenges center around (1) how to determine features that are important to a particular retail business and (2) how to estimate retail sales performance given a new location? The challenges become apparent when the features vary across time. In this light, this study proposed a nonintervening approach by employing feature selection algorithms and subsequently sales prediction through similarity-based methods. The results of prediction were validated by domain experts. In this study, data sets from different sources were transformed and aggregated before an analytics data set that is ready for analysis purpose could be obtained. The data sets included data about feature location, population count, property type, education status, and monthly sales from 96 branches of a telecommunication company in Malaysia. The finding suggested that (1) optimal retail performance can only be achieved through fulfillment of specific location features together with the surrounding trade area characteristics and (2) similarity-based method can provide solution to retail sales prediction.

The PSA screening for 25 years in America is the biggest cohort study in a field of public health.27 We should realize not only the significance of the early diagnosis and treatment of PCa, but also the dramatic decrease in PCaMR from 2002 to 2008. The data from the IARC were especially noteworthy.Moreover, the patients with highly aggressive PCa, who account for more than 30% of all PCa patients, could only be diagnosed earlier by PSA screening. The patients would thus gain the opportunity for earlier treatment and would have a prolonged, higher quality life-span. However, the complications of interventional treatments, including biopsy,radical prostatectomy and/or radiation therapy,will become more avoidable in the near future.According to the supporting evidence for the decrease in PCa mortality in PSA screening, we strongly hope that the USPSTF changes the 'D' recommendation for PSA screening.
