This is a second article about analyzing longitudinal data, which features measurements that are repeatedly taken on subjects at several points in time. The previous article discusses a response-profile analysis, which uses an ANOVA method to determine differences between the means of an experimental group and a placebo group. The
SAS Viya is a cloud-enabled, in-memory analytics engine which allows for rapid analytics insights. Viya utilizes the SAS Cloud Analytics Services (CAS) to perform various actions and tasks. Best of all, CAS is accessible from various interfaces including R. In this blog, I will go through a few blocks one of my notebooks, which moves through an analytics workflow using R and SAS.
A Transformação Digital deixou para trás muitas lacunas processuais e documentais, e trouxe novos desafios à comunidade científica e ao mundo dos Dados de organizações de Tecnologia e de quem dela faz uso para governação de Informação.

If you’re like me, you struggle to buy gifts. Most folks in my inner circle already have everything they need and most of what they want. Most folks, that is, except the tech-lovers. That’s because there’s always something new on the horizon. There’s always a new gadget or program. Or
Site relaunches with improved content, organization and navigation. In 2016, a cross-divisional SAS team created developer.sas.com. Their mission: Build a bridge between SAS (and our software) and open source developers.

With time series data analysis, we can apply moving average methods to predict data points without seasonality. This includes Simple Average (SA), Simple Moving Average (SMA), Weighted Moving Average (WMA), Exponential Moving Average (EMA), etc. For series with a trend but without seasonality, we can use linear, non-linear and autoregressive
This article discusses how to restrict a multivariate function to a linear subspace. This is a useful technique in many situations, including visualizing an objective function that is constrained by linear equalities. For example, the graph to the right is from a previous article about how to evaluate quadratic polynomials.
If you are a caregiver, the holiday season may bring less Peace and Good Tidings, and more Stress and Frustration. If you are already feeling overwhelmed with caregiving responsibilities, the holidays may feel more of a burden than a joy. I think it is fair to say that the holidays are
