Multivariate Analysis of Mixed Data: The R Package PCAmixdata [PDF]
Mixed data arise when observations are described by a mixture of numerical and categorical variables. The R package PCAmixdata extends standard multivariate analysis methods to incorporate this type of data.

On the mixed Cauchy problem with data on singular conics [PDF]
We consider a problem of mixed Cauchy type for certain holomorphic partial differential operators whose principal part $Q_{2p}(D)$ essentially is the (complex) Laplace operator to a power, $\Delta^p$. We pose inital data on a singular conic divisor given

The Fundamental Difference Between Qualitative and Quantitative Data in Mixed Methods Research
Mixed methods research is commonly defined as the combination and integration of qualitative and quantitative data. However, defining these two data types has proven difficult.

mgm: Estimating Time-Varying Mixed Graphical Models in High-Dimensional Data [PDF]
We present the R-package mgm for the estimation of k-order Mixed Graphical Models (MGMs) and mixed Vector Autoregressive (mVAR) models in high-dimensional data. These are a useful extensions of graphical models for only one variable type, since data sets

Existence of optimal boundary control for the Navier-Stokes equations with mixed boundary conditions [PDF]
Variational approaches have been used successfully as a strategy to take advantage from real data measurements. In several applications, this approach gives a means to increase the accuracy of numerical simulations.

Parallel Coordinate Plots of Mixed-Type Data
Parallel coordinate plot of Inselberg (1985) is useful for visualizing dozens of variables, but so far the plot’s applicability is limited to the variables of numerical type. The aim of this study is to extend the parallel coordinate plot so that it can accommodate both numerical and categorical variables.

Advancing Spectral Clustering for Categorical and Mixed-Type Data: Insights and Applications
This study focuses on adapting spectral clustering, a numeric data-clustering technique, for categorical and mixed-type data. The method enhances spectral clustering for categorical and mixed-type data with novel kernel functions, showing improved ...

Clustering of Mixed-Type Data Considering Concept Hierarchies
Most clustering algorithms have been designed only for pure numerical or pure categorical data sets while nowadays many applications generate mixed data. It arises the question how to integrate various types of attributes so that one could efficiently group objects without loss of information.
