About Céline

Doctorate in mathematics and researcher for 7 years, I founded my training, consulting, and statistical expertise company, Statlantic, in 2015 to support companies, local authorities, associations, and technical institutes in their projects involving experimentation or data analysis.

I am also at your disposal to:
- Advise you on the appropriate methodological approach (what are the suitable statistical methods?)
- Implement the entire experimentation phase with design of experiments to choose, order, and optimize tests to be carried out, with the aim of saving time and money while obtaining easily interpretable results.
- Enhance your data through good visualization, meaning thoughtful, adapted, aesthetic, and accessible to all.
- Implement synthetic indicators for decision support tools,
- Analyze your data (multivariate analyses, sensory analysis, etc.) to describe them and make decisions,
- Set up a statistically exploitable survey and analyze the obtained results,
- Assist in the publication of articles containing a section dedicated to statistics on which I can bring my expertise.

A turnkey report, along with all the code (in R) created for you, will be provided at the end of the mission. All of this is, of course, subject to a data confidentiality clause.

Examples of studies conducted:
- Analysis of the effects of restoration plants on invasive plants along railway lines,
- Implementation of a well-being indicator,
- Creation of an iterative program to score e-sports players,
- Implementation and analysis of questionnaires, customer segmentation, recommendations for targeting communication...
- Validation of predictive models, scale validation (sociology, linguistics),
- Study on the performance of skiers...
