I am in need of a biostatistician to complete a project in SAS. Project entails the following: 1. fitting of regression models with epidemiological data, inclusion of the steps and investigating the association of interest, after adjusting for potential confounders and dealing with any effect modifiers. 2. Similar to #1 but different data with different focus All coding must be done in SAS and be able to be explained in a written format. Please contact me for specifics if you are interested.

We need an algorithm that can handle the following use case. Let's suppose I have a set {​n1.......ni}​ and I compute the percentile rank. I want an algorithm that allows me to replace one or more values in the set (i.e. remove set member n5 and replace it with n9. Rather than re-compute the percentile rank across the whole set, I do the following: 1. compare the value the value replaced with the new value 2. based on some difference between the values adjust the percentile rank This can be defined in a statistical formula

This is data in SPSS format. There is about 200 variables. This is a SPSS .sav data file. We need to find if one of the colleges (AG, coded as 4) will significantly impact retention (retainedfall2010, 1=retained, 0=not retained). Thus far I have: However, students from AG have lower retention rate than other faculties with only 71.4%. Assessing Chi-square test for independence (χ^2=6.035, significance = 0.536), retention rate is independent from college type at 95% confidence level. So question is: Can you tell if AG has significant affect on retention? What test to use? What are the values? How do you interpret the values? Thanks!

Dear Freelancer and colleague, I am looking for a medical statistician to help me in analysing particular parameters/variables in a database that i have on specific cancer patients. The database i have are already organized and are on excel sheet and i would like to investigate /study the correlation between two particular variables if possible. In addition , i may kindly ask you to review/edit existing statistical results that i already have done and to get your feedback on it or if you have any suggestions as well. If you are interested then please let me know. Many thanks Enz

I have an Excel sheet of data (please see attached). I also have SPSS. I need the questions in the Excel sheet answered. Need someone who has experience with student retention rates data, if possible. Might need graphs and a summary of data that can be exported from SPSS to Excel.

this is my concept. need help to create a patch with this drug, the patch will be then stuck on human skin which will have micro chip. as this drug when released on the skin will have the reading from the sweat . which will analize the alcohol level . the reading will be then communicated via micro chip to the mobile phone. i need help with the drug - like what will be the ration we need to have it on the patch what will be the patch made of c please check url http://www.psfk.com/2016/08/temporaty-tattoo-warns-you-too-much-to-drink.html for the futher information University of California, San Diego (UCSD) has recently created this

Write 5 articles on trends in the biotech industry, no less than 350 words each. Propose 2-3 keywords for each article along with your suggested titles (must be approved before writing). Keyword density for the content is 2%. This means that your keywords will be used in roughly 2% of each article text. You should have previous writing experience and some academic knowledge of science and biotechnology topics. You will need to be able to refer to statistics in the writing (using text links, not footnotes). All articles must have perfect English grammar and pass Copyscape. Without this, no article will be accepted. Long-term work for well-researched writers.

I need someone to help me with the statistical analysis link to a clinical research project recently completed: 1) Objective 1: To compare the effects of various combinations of four slopes (S=4) and three velocities (V=3) during manual wheelchair prolusion on a treadmill on cardiorespiratory outcome measures among individuals with a spinal cord injury (N=17). a. All excel sheets represent a variable that is relevant for the study (except the randomization order). All variables are continuous variables except the RPE that is categorical/ordinal. b. The values that are in red in the excel sheets were estimated based on a regression equation computed with the data of the participants who completed all combinations. This should be verified before initiating further statistics. c. Comparisons for repeated measures need to be made using the slope and velocity factors and the statistical differences need to be clearly identified with the appropriate tests. d. Strength of the statistics / effect size estimator needs to be included whenever possible 2) Objective 2: To propose an equation estimating the variable VO2 pointe (ml kg min) that is presented on a specific excel sheet. a. A regression equation needs to be generated using the S and V variables. b. Strength of the equation need to be included. c. Possibly compute the future sample size needed to further test the equation generated if possible. The choice of parametric or non-parametric statistitcs needs to be discussed. All statistics performed need to be clearly defined in a paragraph that will be integrated into the manuscript. All results need to be clearly highlighted in a paragraph that will be integrated into the manuscript. Table(s) and/or Figure(s) summarizing the results and key statistics need(s) to be prepared for the submission of the manuscript. The use of a p-value of 0.05 is needed and should be corrected whenever multiple comparisons are being performed. SPSS format is preferred for the statistical analyses.
