Material: Basic Elements of statistics: descriptive statistics, elements of probability, statistical distributions, inference in normal populations (tests and confidence intervals for one and two means or variances) , ANOVA 1, simple and multiple regression .

Courses : LBIR1203 and LBIR1304 : Probability and Statistics 1 and 2

Main themes

1 . Statistics for measurement methods: reminders of Metrology (error types, quantification of error uncertainty, error propagation' ), variance components estimation by ANOVA, control charts, simple linear calibration.

 

2 . Experimental design in product and process development: Methodology , multiple regression and multiple response optimization , factorial designs and derivatives, screening designs, response surface designs , mixture designs and  optimal designs

3 . Multivariate statistical methods in chemistry: principal component analysis , partial least squares (PLS) , clustering, discriminant analysis and its application to multivariate calibration in analytical chemistry

4 . Applications with the JMP software

At the end of the course students will be able to :

-        Explain the interest of statistical tools in the work of the chemical engineer

-        Explain the purpose and usage of each statistical tool seen in the course. select the one adapted to a given situation and calculate related parameters.

-        Demonstrate their understanding of main course concepts by solving methodological exercises

-        Use JMP software to apply the methods presented in the course.

-        Interpret the results of a statistical analysis in the context of a case study in chemistry or life science.

For specific tools

-        Use statistical tools to quantify the precision of a measurement method

-        Organise an experiment with the design of experiment methodology from the design selection to the statistical analysis

-        Summarize / visualize large data sets (eg from spectral analytical methods) using multivariate statistical tools
