Statistical Problems in the Analysis of Unequally Spaced Data

P. Tavella, M. Leonardi

Abstract:	The statistical analysis of irregularly spaced data or the handling of series with missing data asks for particular care because results may be biased In particular, in PTTI applications, two points seem to be addressed: - The noise analysis in term of Allan or related variances; - The estimation of a missing datum on a particular date. Both these issues are examined in the particular case of the current TWSTT measurement, by means of an analytical and theoretical approach that can be of more general interest. Some numerical estimates based on the TWSTT measures are eventually reported.
