We have identified a Y-chromosomal lineage with several unusual features. It was found in 16 populations throughout a large region of Asia, stretching from the Pacific to the Caspian Sea, and was present at high frequency: approximately 8% of the men in this region carry it, and it thus makes up approximately 0.5% of the world total. The pattern of(More)
In this paper, we propose an improved combined forecasting model integrates the merits of data pretreatment, combined model and Markov chain, known as Markov combined model. The moving average is used for the data pretreatment or determination of trend, combined model is designed for the trend forecasting, and the Markov chain is employed for modifying the(More)
—In this paper, we study the time series techniques for the monthly precipitation forecasting. The techniques used in this study are moving average procedure, support vector regression machine, and seasonal autoregressive integrated moving average model and hybrid procedure. Firstly, the moving average procedure is employed to find the trend; secondly, the(More)
