cheaper to collect as well as more time efficient as compared to primary source data. The nature of the data above is relevant to what Hayward is searching for. Knowing the spending trend of the entire population on the specific country could be very useful to determine if it is the right time/ market to venture in. ________________________________________________________________________________________________________ We would recommend probability samples design to non-probability samples

Monte Carlo simulation would support this conclusion. If you were to develop a spreadsheet with a random number generator resulting in 0 for “heads” and 1 for “tails,” then have the spreadsheet recalculate a million times, you would see that very close to 50% of the recalculations resulted in 0 (“heads”) and the other 50% in 1 (“tails”). The basic approach would be to build a spreadsheet with random number generators that replicate the probabilities in the model. This is the essence of simulation:

predominant belief among real estate professionals is that appraisal error is random. This belief materially influences investor attitudes toward portfolio management and the valuation process itself. Lack of understanding of the relative magnitudes of random and nonrandom components of total appraisal error has consequences for optimal portfolio strategies. For example, investors who deem the bulk of total appraisal error to be random may reasonably conclude that error in estimates is beyond their control

Forecasting the USD/COP Exchange Rate: A Random Walk with a Variable Drift Peter Rowland Banco de la República* Abstract This study develops three exchange rate models as well as a simple statistical model defined as a random walk with a variable drift. The exchange rate models all use the purchasing power parity hypothesis to account for the long-term relationships between prices and the exchange rate, together with error correction models to represent any shortterm dynamics. The models are

and see what their experiences tell us. To conduct a survey, I would have people answer the questions of: Have you ever had sex with someone random while sober? Have you ever had sex with a random person while intoxicated? Have you ever dated this random person after you had sex? With these questions I hope to find the idea that most people hook up with random people when they are intoxicated, and with this finding it should show a link between the idea of sex and college students. What I also believe

Tutorial on Classification Igor Baskin and Alexandre Varnek Introduction The tutorial demonstrates possibilities offered by the Weka software to build classification models for SAR (Structure-Activity Relationships) analysis. Two types of classification tasks will be considered – two-class and multi-class classification. In all cases protein-ligand binding data will analyzed, ligands exhibiting strong binding affinity towards a certain protein being considered as “active” with respect to it
