Piece–wise Information for the Truncated Cosinor Model

The target of this paper is to examine the average–per–observation information matrix for the truncated cosinor model. We state and prove an orthogonal decomposition of this matrix so that the total information can be obtained as a result of three particular parts. The total information is presented piece–wise in three components. Each component is easily represented. Therefore the total information can be checked through three different points on the collection of the information.
