This is a ope access article distributed uder the Creative Commos Attributio Licese, which permits urestricted use, distributio, ad reproductio i ay medium, provided the origial wor is properly cited. Necessary ad sufficiet coditios are give for the complete covergece of maximal sums of idetically distributed egatively associated radom variables. The coditios are expressed i terms of itegrability of radom variables. Proofs are based o ew maximal iequalities for sums of bouded egatively associated radom variables. 1. Itroductio The paper by Hsu ad Robbis 1 iitiated a great iterest to the complete covergece of sums of idepedet radom variables. Their research was cotiued by Erdös, 3, Spitzer 4, ad Baum ad Katz 5. Kruglov et al. 6 proved two geeral theorems that provide sufficiet coditios for the complete covergece for sums of arrays of row-wise idepedet radom variables. I the paper of Kruglov ad Volodi 7, a criterio was proved for the complete covergece of sums of idepedet idetically distributed radom variable i a rather geeral settig. Taylor et al. 8 ad Che et al. 9, 10 demostrated that may ow sufficiet coditios for complete covergece of sums of idepedet radom variables ca be trasformed to sufficiet coditios for the complete covergece of sums of egatively associated radom variables. Here we give ecessary ad sufficiet coditios for the complete covergece of maximal sums of egatively associated idetically distributed radom variables. They resemble the criterios preseted by Baum ad Katz 5 ad by Kruglov ad Volodi 7 for the complete covergece of sums of idepedet idetically distributed radom variables. Theorems.3 ad.5 are our mai results. Theorem.3 is ew eve for idepedet radom variables.
2 Joural of Probability ad Statistics I what follows we assume that all radom variables uder cosideratio are defied o a probability space Ω, F,P. We use stadard otatios, i particular, I A deotes the idicator fuctio of a set A Ω. Recall the otio of egatively associated radom variables ad some properties of such radom variables. Defiitio 1.1. Radom variables X 1,...,X are called egatively associated if Cov f X i1,...,x i,g X j1,...,x jm for ay pair of oempty disjoit subsets A i 1,...,i ad B j 1,...,j m, m, of the set 1,..., ad for ay bouded coordiate-wise icreasig real fuctios f x i1,...,x i ad g x j1,...,x jm,x 1,...,x R,. Radom variables X, N 1,,..., are egatively associated if for ay N radom variables X 1,...,X are egatively associated. I this defiitio the coordiate-wise icreasig fuctios f ad g may be replaced by coordiate-wise decreasig fuctios. Ideed, if f ad g are coordiate-wise decreasig fuctios, the f ad g are coordiate-wise icreasig fuctios ad the covariace 1.1 coicides with the covariace for f ad g. Theorem A. Let X, N, be egatively associated radom variables. The for every a,b R,a b, the radom variables Y a I,a X X I a,b X b I b, X, N, are egatively associated. For every N ad x 1,...,x R, the iequalities PX 1 x 1,...,X x PX 1 x 1,...,X x PX x, PX x 1. hold. Proof. It ca be foud i Taylor et al. 8. Theorem B. Let X be egatively associated radom variables. Let X, N, be idepedet radom variables such that X ad X are idetically distributed for every 1,...,.The E expx 1 X E exp X 1 X. 1.3 If E X p < ad EX 0 for all 1,...,ad for some p 1, the r p E max X E 1 r X p, N. 1.4 Proof. It ca be foud i Qi-Ma Shao 11.

A oegative fuctio h x,x 0,, belogs to the class H q for some q 0, if it is odecreasig, is ot equal to zero idetically, ad y /q 1 lim sup y h y h x lim sup x h x <, y h x x /q dx <..1. The class H q cotais all odecreasig oegative fuctios slowly varyig at ifiity which are ot equal to zero idetically, ad i particular, l β 1 x with β>0. The fuctios x α ad x α l β 1 x with α 0, /q 1 ad β>0arealsoih q. Remar.. If a oegative fuctio h x,x 0,, is odecreasig ad satisfies coditio.1, the h x Δx l.3 for all x greater tha some x 0 1 ad for some Δ > 0adl>0. Proof. We may assume that h x > 0 for all x greater tha some x 0 1. From coditio.1, it follows that sup x x0 h x /h x d<. Choose a umber l>0 such that d l. If x x 0, the x 0 x< x 0 for some N ad h x h x 0 d h x 0 l h x 0 l x l h x 0. Iequality.3 holds for all x x 0 with Δ l h x 0. Theorem.3. Let X, N, be egatively associated idetically distributed radom variables, S X 1 X, 0 <q<,r > 1. Let h x,x 0,, be a fuctio which is odecreasig, is ot equal to zero idetically, ad satisfies coditio.1. The the followig coditios are equivalet: E X 1 rq h X 1 q <, EX 1 0, for q 1,.4 r h P max S >ε 1/q <, ε >0,.5 1 r h P sup 1/q S >ε <, ε >0..6

Theorem.5. Let X, N, be egatively associated idetically distributed radom variables, S X 1 X,h H q, 0 <q<,r 1. The the followig coditios are equivalet: E X 1 rq h X 1 q <, EX 1 0, for q 1,.8 r h P max S >ε 1/q <, ε > Corollary.6. Let X, N, be egatively associated idetically distributed radom variables, S X 1 X, 0 <q<,β 0. The followig coditios are equivalet: E X 1 q l X 1 βq <, EX 1 0, for q 1, l β P max S >ε 1/q <, ε > Proof of Theorem.3. The theorem is obvious if the radom variable X 1 is degeerate, that is, PX 1 cost. 1. From ow o we suppose that the radom variable X 1 is ot degeerate.
