For this purpose the deterministic model transfers to stochastic models by adding different noise terms in force and then these models are solved analytically and numerically. Finally an investigation is undertaken to examine the parameter estimation problem of second order stochastic differential equations when some of the measurements are unavailable or missing data. Several simulation results are presented to illustrate the performance of the estimators. %U https://ijsts.shirazu.ac.ir/article_1596_86807fca2b8e79ad581519d65795e2a9.pdf
