• Clinical Trial Design
Clinical trial design and implementation can be very difficult. Since these trials often deal with medication, surgeries, and other treatment options, there are many ethical considerations that need ....
• Logistic Regression
Logistic regression, or logistic discriminant analysis, is a variation of standard regression that is used when the dependent variable is a dichotomy (that is, yes or no). Moreover, like regression a....
• Statisticians
Statisticians are a highly-qualified group of professionals who design, study, and analyze data collections in order to draw unbiased conclusions. While many students of statistics enter work in a va....
• Clinical Research Trials
Clinical research trials can come in several forms of assessment. These trials typically examine the effects of drugs or treatment forms using a control group and an experimental group to draw conclus....
• Generalized Estimating Equations
If you are working with panel data and longitudinal analysis and need to manage the correlation structure, you should consider using generalized estimating equations (GEE). In fact, generalized estima....
• Biostatistician
A biostatistician uses his or her knowledge of statistics to study the realms of biology, disease and health. Much like the work of other statisticians in various disciplines, biostatiscians draft st....
• Mathematical Modeling
Mathematical modeling describes the process of representation arrived at by mathematical means, to create a more acute understanding of a given phenomenon. In this process, the goal is to "match" sym....
• Linear Regression Models
By fitting a linear equation to the observed data, linear regression models try to represent the relationship between two variables. These models are an effective way to describe complex relationships....
• Statistical Analysis
Statistical analysis is useful not only in drawing conclusions from existing data, but also from drawing inferences and probable predictions in uncertain situations. There are many different type of ....
• Statistical Modeling
Statistical modeling is a numerical representation of reality that estimates an unknown characteristic. Essentially, it is a way to quantitatively describe and/or predict a physical or behavior pheno....
