The talk will go through the following topipcs: - Least squares estimation, Gauss-Markov theorem - Broken lines, Chi² minimization - Test statistics (Chi², p-values) - Kalman Filtering - Track finding with the combinatorial Kalman filter - Outlier rejection, Deterministic Annealing Filter - System parameters and fitted chi² - Alignment - Estimation of resolution and material distribution

A track finding processor based on fast Hough transformation for the LPTPC has been implemented in ILCSOFT. This has been successfully tried on beam telescope data too.

The physics performance of the CMS experiment depends crucially on its tracking detector, which consists of 25000 silicon sensors. In order to achieve the required tracking precision, it is necessary to align the positions and orientations of the sensors at micrometer level, which involves the adjustment of approximately 200000 parameters. They are determined simultaneously in a track-based...
