    Good communication and trustworthy in terms of delivering work. Very polite. However, it feels the job was attempted without giving good attention to the questions and their exact requirements. This is reflected on the lack of quality of the overall work which will probably lose lots of marks if submitted like that. I had to consult other people to complete the job myself.

    Eric, I understand you and Ken have been in contact. We would like to offer you a project where we would have you cross-check some analysis that we will have, look for any alternatives we may have missed, verify our findings, that kind of thing. I would estimate 2-3 hours of work on this particular project, but we would be willing to listen if you felt differently after looking at the data and assessing the scope. Again, we&quot;re hopeful that this might likewise lead to additional projects along these lines. If this is of interest, I am uploading a confidentiality agreement that we would ask you to sign and return (electronically would be fine).

    Hi,Can you solve this problem.. Let me know asap.The mortgage meltdown of 2007-2008 caused financial ruin for many banking institutions. The housing bubble had burst and confidence in lending to the everyday consumer had dwindled. As our bank looks to strengthen its lending program, we need to assess our past practices. The Bank Manager would like to increase our mortgage program by 15% (mortgages underwritten). But how have we done since 2001? What were the key indicators? What would be your analysis plan to help manage this issue? What analysis plan would you recommend using SAS as a tool for data mining and analysis.What would be your strategy on employing and managing the analysis required?

Evaluation of a measles vaccine campaign by oral-fluid surveys in a rural Kenyan district: interpretation of antibody prevalence data using mixture models

Cambridge University Press

We evaluated the effectiveness of a measles vaccine campaign in rural Kenya, based on oral-fluid surveys and mixture-modelling analysis. Specimens were collected from 886 children aged 9 months to 14 years pre-campaign and from a comparison sample of 598 children aged 6 months post-campaign. Quantitative measles-specific antibody data were obtained by commercial kit. The estimated proportions of measles-specific antibody negative in children aged 0-4, 5-9 and 10-14 years were 51%, 42% and 27%, respectively,
