Automatic identification of variable types – Identify variables in the Multiple variables data table as continuous, categorical, or label values.

Text information in the data table – Enter data directly as text.

Instead of coding a variable like “0” and “1”, simply enter “Male” and “Female” directly in the data table

Automatic variable encoding – Enter your data and let Prism take care of the rest.

Prism will automatically encode categorical text variables into numeric “dummy” variables Often times in research we find ourselves with an abundance of information on different variables from our experiments. As a simple example, imagine measuring the blood pressure of individuals after giving them either an experimental drug intended to reduce blood pressure or a placebo.

It’s likely that in addition to the recorded blood pressure measurements, you also recorded a wealth of information on each subject’s age, height, weight, gender, race, and any number of other potential variables. Numerous statistical techniques are designed to analyze this sort of “multiple variables” data, such as multiple linear regression and multiple logistic regression. Using these sorts of “multiple variables” analyses means you can explore the outcome of interest without wasting any potentially useful information. In order to facilitate this increased density of data information, Prism offers our Multiple variables data table to house data in a standard data structure that is used almost universally by other statistics software and packages out there (such as R, SPSS, and MATLAB). In this format, each column represents a different variable, while each row represents a different subject (measurements of each variable for each subject get placed into their appropriate column on that subject’s row). Sometimes, the amount of variables collected far outweighs the number of subjects that were available to study.

Consider gene expression studies in which expression levels of hundreds or thousands of different genes were measured from subjects divided into two groups: a treatment group and a control group. There may simply be too many variables to fit a model to the data.
