'RStudio' Addin for Building Shiny Apps per Drag & Drop
This 'RStudio' addin makes the creation of 'Shiny' and 'ShinyDashboard' apps more efficient. Besides the necessary folder structure, entire apps can be created using a drag and drop interface and customized with respect to a specific use case. The addin allows the export of the required user interface and server code at any time. By allowing the creation of modules, the addin can be used throughout the entire app development process.
Material Management
A set of functions, classes and methods for performing ABC and ABC/XYZ analyses, identifying overperforming, underperforming and constantly performing items, and plotting, analyzing as well as predicting the temporal development of items.
Extraction and Analysis of Data from the Bitcoin Cash (BCH) Blockchain
Issues RPC-JSON calls to 'bitcoind', the daemon of Bitcoin Cash (BCH), to extract transaction data from the blockchain. BCH is a fork of Bitcoin that permits a greater number of transactions per second. A BCH daemon is available under an MIT license from the Bitcoin Unlimited website < https://www.bitcoinunlimited.info>.
Implementation of BDAT Tree Taper Fortran Functions
Implementing the BDAT tree taper Fortran routines, which were
developed for the German National Forest Inventory (NFI), to calculate
diameters, volume, assortments, double bark thickness and biomass for
different tree species based on tree characteristics and sorting information.
See Kublin (2003)
Portfolio Allocation and Risk Management Applications
Provision of a set of models and methods for use in the allocation and management of capital in financial portfolios.
Correction Factors for Tree Plot Areas Intersected by Stand Boundaries
The German national forest inventory uses angle count sampling, a sampling method first published as `Bitterlich, W.: Die Winkelzählmessung. Allgemeine Forst- und Holzwirtschaftliche Zeitung, 58. Jahrg., Folge 11/12 vom Juni 1947` and extended by Grosenbaugh (< https://academic.oup.com/jof/article-abstract/50/1/32/4684174>) as probability proportional to size sampling. When plots are located near stand boundaries, their sizes and hence their probabilities need to be corrected.
Fitting Structural Equation Mixture Models
Estimation of structural equation models with nonlinear effects and underlying nonnormal distributions.
Statistics for Holland's Theory of Vocational Choice
Offers a convenient way to compute parameters in the framework of the theory of vocational choice introduced by J.L. Holland, (1997). A comprehensive summary to this theory of vocational choice is given in Holland, J.L. (1997). Making vocational choices. A theory of vocational personalities and work environments. Lutz, FL: Psychological Assessment.
