Abstract
One of the important topics in Drosophila melanogaster is statistical analysis of bicoid protein gradient. The bicoid protein gradient plays an important role in the segmentation stage of embryo development in the head and thorax and also has considerable noise. Therefore, it has been considered by many researchers. In this paper the state space model and Kalman filter algorithms are used for noise elimination and smoothing bicoid gene expression. The state-space allows the unobserved variables, each with a specific interpretation, to be included in the estimate with the observed model and can be analyzed using the Kalman filter algorithm. Then, the less noise bicoid gene expression are used for forecast by singular spectrum analysis (SSA) method. The results with strong evidence indicate that the proposed method can be considered as a powerful technique in the analysis and prediction of gene expression measurements.
