Expert in multivariate analysis for weighting indicators based on qualitative data
We need to estimate weights for quality indicators in order to get a general indicator. These quality indicators are based on qualitative data. We already have collected evaluation questionnaires from some colleagues. The responses of the questions of these questionnaires are used to build our quality indicators about quality features of our products. These responses are ordinal scales that are different from one question to another.
Weighting quality indicators should be based on data already collected. Thus, a statistical method based on multivariate analysis of qualitative data should be applied to get these weights.
This job consists of preparing a technical document specifying the procedure to weighting the quality indicators. The procedure must be a methodological and technical document at the same time (describing all statistical methods used and the scripts, syntaxes and packages used to calculate the weights by some statistical software like “R”). This document should be clear enough to reproduce it with real data in other projects. The document should have good references to the sources used to elaborate it. All assumptions should be founded on solid and widely-recognized statistical methods. An example of the quality indicators is attached.
