I think that the probabilistic and sensitivity analysis may be enough. But, for intensive results and comparisons, you have to consider the statistical analysis. The choice may depend on the nature of your application and research work.
Thank you very much Doctor. The truth is that we do not have on-site readings, so it is not possible to make a true comparison, so I approached this analysis in the hope that this analysis is sufficient.
It depends on the objectives and audience/readers of your report. It is mainly a stand-alone analysis in the field of parameters or models uncertainty.
Some time stability analysis and other mathematical analyses are also useful for the confirmation of the probabilistic and sensitivity analysis results or for more accuracy.
Probability deals with predicting the likelihood of future events, while statistics involves the analysis of the frequency of past events. Sensitivity analysis is a numerical tool to gain/improve understanding of a function we don't know the shape of ie factor of safety function. All different concepts.
