In my book Simulating Data with SAS, I discuss a relationship between the skewness and kurtosis of probability distributions that might not be familiar to some statistical programmers. Namely, the skewness and kurtosis of a probability distribution are not independent. If κ is the full kurtosis of a distribution and
We asked our partners at the Cornell Center for Hospitality Research to comment on what they are seeing in terms of trends that will impact the hospitality industry in 2015. Cathy Enz, full professor in strategy and The Lewis G. Schaeneman Jr. Professor of Innovation and Dynamic Management at the

You’ve heard about the smart grid, but what is it that makes the grid smart? I’ve been working on a project with Duke Energy and NC State University doing time-series analysis on data from Phasor Measurement Units (PMUs) that illustrates the intelligence in the grid as well as an interesting
In my last post, I pointed out that we data quality practitioners want to apply data quality assertions to data instances to validate data in process, but the dynamic nature of data must be contrasted with our assumptions about how quality measures are applied to static records. In practice, the
Back in the day when the prison system forced inmates to perform "hard labor", folks would say (of someone in prison): "He's busy making little ones out of big ones." This evokes the cliché image of inmates who are chained together, forced to swing a chisel to break large rocks
In the SAS DATA step, all variables are scalar quantities. Consequently, an IF-THEN/ELSE statement that evaluates a logical expression is unambiguous. For example, the following DATA step statements print "c=5 is TRUE" to the log if the variable c is equal to 5: if c=5 then put "c=5 is TRUE";
