If you have any questions or concerns, please contact Liang Shan, PhD, Research Biostatistician.

Statistical Consulting and Collaboration Guidelines

PI Responsibility

  • I will provide at least 1-hour notice to all parties if I must cancel a meeting or arrive late for any reason.
  • I understand that statistical consulting deals with simple questions that could be solved within a short period (approximately 0.5-1 hour) and does not need repeated scheduled meetings with the biostatistician; whereas statistical collaboration answers research questions and it requires long-term partnership with the biostatistician, preferably from the initial stage, role of the biostatistician may be Co-PI or Co-Investigator.
  • I understand that the biostatistician primarily provides advice and assistance for my project and DOES NOT typically clean or format data.
  • To make the most of my time with the biostatistician, I will try to come prepared to the first meeting with research background, research goals and questions, research papers that may assist the biostatistician in understanding my research, and results of any analyses already performed—including plots or graphs.
  • I understand that many problems cannot be solved in just one meeting and am prepared to meet several times with the biostatistician if needed.
  • I understand that request should be received well ahead of the proposed deadline to receive proper attention. In cases of emergency, and subject to the availability of the biostatistician, limited assistance may be provided on short notice. However, there is no guarantee that every requested deadline can be honored.
  • I understand that projects are processed based on the request date (first come, first serve) and hard deadlines. In addition, projects may be triaged based on priorities of the administration team.
  • I understand that I cannot receive assistance on class projects or homework.

Biostatistician Responsibility

  • I will provide at least 1-hour notice to all parties if I must cancel a meeting or arrive late for any reason.
  • I will provide assistance in a timely manner to the collaborators.
  • I will provide advice in data formatting or cleaning if needed.
  • I will advise the collaborators on appropriate study design or analyses for their data and assist in performing the analyses as time allows.
  • I will discuss with the collaborators statistical assumptions made and the potential drawbacks of different analyses.
  • I will attempt to explain the statistical methods used and results in a way that the collaborators understand.
