Hi,

Mithilesh was of great assistance in answering some questions about the use of the program STATA and explaining the significance of various statistical tests (I needed to perform a logistic regression and needed to know the signifcance of chi squared and fischer's exact tests on my data). Thanks alot for your help!

For the past few months, Mithilesh has provided valuable advice and insight into the analysis of my database. His knowledge and explanation of the various statistical tools have been clear and beneficial to me. Of particular note is his thorough knowledge of multivariate logistic regression and Cox regression analysis.

His consultation is certainly recommended.

Mithilesh Dronavilli has aided myself and other medical research students for the last few months with the statistical analysis of our projects. His advice has always been clear and helpful.

I would recommend his services as a biostatistician to anyone.

Hi Mithilesh,

 Thank you for the advice you gave me with statistical analysis for my research project. Your assistance with multivariate logistic regression was particularly insightful. Cheers!

With regards,

The Sample Size required is governed by many factors. Some of the basic factors include the required power, the effect size that is required to be detected, one tail or two tailed test, the proportion of the sample in each group.

In multivariate analysis samplesize is extremetly complicated and is partly detremined by the correlation of each of the predictor variables with themselves and the outcome. 

There are many resources available on sample size and a simple google search will make you informed at an intermediate level.
