The author presents an introduction to the statistical analysis of experimental data by means of Monte Carlo simulations. After a description of the #chi#"2 test of a hypothesis the least-square and maximum-likelihood fits to Monte Carlo distributions are described. Then unfolding is described. Finally confidence intervals are studied, and the comp...

The best fits to data which are affected by systematic uncertainties on the normalization factor have the tendency to produce curves lower than expected, if the covariance matrix of the data points is used in the definition of the #chi#"2. This paper shows that the effect is a direct consequence of the hypothesis used to estimate the empirical cova...
