Prognosis = a forecast of the future course, or outcome, of a situation; a prediction ” (Daigle 2014, p. 7) “

“Prognostics is the ability to predict future events, conditional on anticipated usage and environmental conditions, significantly contributes to a system’s resilience for safe and efficient operation.” (Sankararaman/Abhinav/Goebel 2014, p. 533) “(…)

To prognosticate is “to foretell from signs or symptoms: predict” (Merriam Webster Dictionary 2019)

Prediction and Forecasting

“Prediction is concerned with estimating the outcomes for unseen data. (…) you fit a model to a training data set, which results in an estimator f^(x) that can make predictions for new samples x.” (Döring 2018)

“Forecasting is a sub-discipline of prediction in which we are making predictions about the future, on the basis of time-series data.” (Döring 2018)

DevOps and Big Data

In the era of big data and big code numerous open source tools, libraries, frameworks and code repositories allow IT experts to follow the DevOps approach, where time consuming developing tasks such as deployment, installation, configuration and the set up are automatized.

“Big Code” and open-source Tools

Code repositories offer pre-built, refactorable and reusable working examples for the easy usage within the enterprise architecture. A large set of standardized models, methods, techniques and practices allow developers and testers to perform mathematical operations and analysis such as forecasting and AI with an ease on large amounts of data. The magic lies in the huge number of free usable open source tools and libraries with to access to the APIs of numerous providers of data and code.

Predictive Analytics

PROQNOSTIX enables companies to perform analysis on data, driven by a business goal to predict future developments based on the data, most appropriate regarding the business goals from the perspective of predictive analytics.

Discipline of Econometrics

Thus PROQNOSTIX offers products and services in the discipline of econometrics, defined as “the forecasting of macroeconomic variables, such as interest rates, inflation rates, gross domestic product (GDP) and a collection of methods for the forecasting of economic time series and the prediction of economic theories.” (cf. Wooldridge 2009, p. 1f)

Data can be structured as time series or as cross-sectionnal data.

Time Series Data

Time series data consist of observations on stock prices, money supply, consumer price index, annual homecide rates, automobile sales etc. (cf. Wooldridge 2009, p. 8)

Cross-sectional Data

“Cross-sectional data consists of a sample of individuals, households, firms, cities, states, countries, or a variety of other units, taken at a given point in time. Sometimes, the data on all units do not correspond to precisely the same time period. For example, several families may be surveyed during different weeks within a year, In a pure cross-sectional analysis, we would ignore any minor timing differences in collecting the data. If a set of families was surveyed during different weeks of the same year, we would still view this as a cross-sectional data set.” (cf. Wooldridge 2009, p. 5)

The Art of Forecasts and Predictions

The arts of forecasting is the determination of the best fitting model with the most adequate parameters for a given business goal. There is a large set of models in AI and further emerging technologies, such as blockchain, IoT, serverless computing etc. to be discovered.

Modeling Forecasts

All models will perform differently depending on which application domain they are applied to. The job of the forecaster is to compare those models most suitable for a given issue and to optimize the parameters of the model. The next figure shows an hierarchical overview of widely used forecasting methods and the underlying taxonomy (see Fig. 1):

Industrial Branches

Potentially each industrial branch is affected by the potential for competitiveness. We now focus on three branches in order to demonstrate the potential of the application of products and services of PROQNOSTIX:

  • Banking Industry:
    • Forecastings for investments in the stock markets
    • Forecastings of the creditworthiness
  • Geodata
    • Real estate prices
    • Demographics
    • etc.
  • Marketing
    • Search Engine Optimization
    • Social Media Analysis
    • etc.

How PROQNOSTIX proceeds with nubank.de

Nubank.de is a side project of ask-a-woman.com (AAW). Nubank.de typifies a model bank on the basis of a scientific research conducted by experts of AAW. In this research project

  1. PROQNOSTIX supports the definition of the companies business goals cooperating with the domain experts of nubank.de. The evaluation of the potential of big data repositories for the application of mathematical and AI-based methods and practices e. g. for forecasts performed in an software engineering environment provided by PROQNOSTIX is part of the analysis stage.
  2. Definition of technology stack, methods, libraries, tools, resources, tasks, roles etc.

We first give an overview on potential application areas and then focus on the requesting companies branch.

As an example the banking industry is likely to be interested in

  • forecasts for investments in the stock markets and therefore the companies key performance indicators,
  • forecasts of the creditworthiness of a private person or a company,
  • the application of AI methods etc.

The Geo Information Systems (GIS) sector is applying forecasts and other mathematical methods on the development of

  • Real estate prices
  • Demographics
  • etc.

And marketing departments and agencies are interested in the success of their campaigns in the fields of

  • Search Engine Optimization
  • Social Media Analytics
  • etc.


In the second part of the workshop we address primarily methods, techniques and best practices of Mathematics, Informatics and Business administration, but we´ll also take into account methods from other branches.

Methods, techniques and practices of mathematics are as follows:
