It contains:
There are two modes of interaction with the analytics; spreadsheet and workspace. For ad-hoc analysis that does not need to be duplicated, users can import data into a spreadsheet and interact with menus, variables, and rows of data. The workspace is a visual analytic workflow management tool and is recommended. This allows work to be saved and reused. No coding is needed to complete a workspace. And for the users who need to manage their code, the workspace has a "code node" which can execute C#, Python, or R code.
The Data Health Check node (data profiling) explores values, value ranges, discrete text lables, missing data, outliers, etc.. on every variable. The results of this analyses is a diagnostic report. This node can also be configured to automate fix the data problems uncovered by the analyses.
Additional options to transform and clean are available; remove duplicates, recode, rank, merge, process invariant variables, recode outliers, missing data inputation, recode missing data, subset, sample, etc..
Box-Cox is available to transform variables so that they have a distribution as close to normality as possible (Box and Cox, 1964). This allows the use of algorithms, like regression analysis, that only work with a normal distribution.
A workspace is a no code tool that:
The workspace can also be extended with R, C# or Python coding.
2D and 3D visualizations are available with the product; histogram, line, scatterplot, means with error, bag plots, quantile-quantile (beta, exponential, extreme, gamma, lognormal, normal, Rayleigh, Weibull), variability, contour, wafer, normal probability, etc.. Interactive dashboards are not available within this product. TIBCO Spotfire® licensing is purchased separately.
