Title: Simulation of Statistical Fluctuations in the Spin Precession Measurements at RHIC

Measurements of the driven spin coherent precession S x(t)=S x (0) - S x (1) sin(ωt+φ 0) were initiated in RHIC Run13. The expected value of the precession amplitude S x (1) ~ 2 x 10 -4 is about the statistical error in a single measurement and data fit gives a biased estimate of the S x (1). For a proper statistical interpretation of the results of the several measurements, statistical fluctuations were studied using Monte-Carlo simulation. Preliminary results of the spin precession measurements in RHIC Run13 are presented.
