Summary: Through the modeling, herein, we suggest the adaptation of some classic distribution densities to possible situations in real cases. The classic distribution densities are truncated, obviously keeping the properties of a density. The new expressions of the density, having one extra parameter, can better approximate the experimental data. Further, we introduced the Cauchy truncated distributions and the normal, accompanied by numerical examples.
