The course aims to supply the main concepts required for an understanding of the fundamental concepts of statistical inference from experimental data, and optimization theory of functions.
The student will be able to deal with problems related to the parameter estimation for linear and non-linear models, and she/he will be able to (i) interpret and select the best model for the description of the experimental reality, (ii) identify the most appropriate parametric conditions for a given objective function.
The student will be capable of recognizing the statistical nature of an engineering problem and he will have gained a sensitivity in interpreting the experimental data and she/he can find out the degree of confidence about the conclusions that can be drawn from his analysis.

In case it is necessary to prevent risk of infection COVID-19, teaching will be delivered online, as well as in presence, using a blended teaching method. If prevention measures need to be taken, at the beginning of the semester, each student can opt, with a binding choice, for face-to-face or distance teaching. Depending on the availability of the classrooms and the number of students, who selected the presence mode, there may be a shift for access to the classroom.
Verification of learning
Knowledge and understanding of the student is evaluated through evaluation of a team paper work and an oral interview that will be held in-presence or remotely using computer aids.
The student is required to demonstrate to know the theory of the statistics applied to the analysis of experimental data and the parameter inference for mathematical models. It is important that the student has a deep knowledge of the typical chemical engineering processes. The answers need to be motivated using the theoretical concepts tackled in the course. The student is also required to analyze particular situations proposed by the teacher during the exam. It is also evaluated the line of reasoning for the student presentation and the use of a proper technical language.
The student is evaluated according to the following criteria:
- knowledge and basic understanding of the concepts: 18/30-21/30;
- knowledge and understanding and ability of applying knowledge: 23/30-26/30;
- knowledge and understanding, ability of applying knowledge and ability to handle complex problem of model inference: 27/30-30/30.

A Facebook group has been also created:
with several purposes including: (i) link to other educational material available on the network and (ii) stimulate the discussion among the students and between students and the teacher.
