Prior to distributed DATA Step, DATA Step programmers never had to think about achieving repeatable results because DATA Step ran single-threaded and the source SAS7BDAT dataset was stored on disk. But if you need to obtain repeatable results in DATA Step code that runs distributed in CAS, this post provides a workaround that you'll want to keep handy.Read More
An ROC curve graphically summarizes the tradeoff between true positives and true negatives for a rule or model that predicts a binary response variable. An ROC curve is a parametric curve that is constructed by varying the cutpoint value at which estimated probabilities are considered to predict the binary event. [...]

Previously, I have written articles on how we could display more subject response data along with the traditional WaterFall graph showing the best "Change from Baseline". This is in response to the desire to see data like treatment duration for each subject in the same graph. Otherwise, investigators have to [...]Read More
The SGPLOT procedure enables you to use the value of a response variable to color markers or areas in a graph. For example, you can use the COLORRESPONSE= option to define a variable whose values will be used to color markers in a scatter plot or cells in a heat [...]

Emerging technologies enable retailers to differentiate with data and analytics that enhance the customer experience. In four key ways, retailers can partner with the analytics using data associated with past and present interactions and, through systemic innovation capitalize on future customer interactions.

When solving optimization problems, it is harder to specify a constrained optimization than an unconstrained one. A constrained optimization requires that you specify multiple constraints. One little typo or a missing minus sign can result in an infeasible problem or a solution that is unrelated to the true problem. This [...]
