The channel has been simulated by using the statistical model based on the sum of sinusoids (SoS [24], which derives from the well-known Jakes model.
Numerical analysis and model experiment show that the crack occurring in the arch dam will reduce natural frequencies and can be detected by using the statistical neural network based on the information of such reduction.
Twenty data sets were imputed for a categorical variable using the statistical software package Stata, based on age when invited, screening area, type of invitation (first call or routine recall), ward of residence, socioeconomic deprivation and screening attendance.
QoL data was analyzed based on the guideline provided by Ferrans and Power using the statistical program Syntax for SPSS-PC based manual analysis [ 26].
OPLS modelling was performed using the statistical software R [ 56] based on in-house produced code.
Correlation analyses were carried out using Analyse-it for Excel [ 47], using the free statistical environment R [ 48] or using the statistical functions available in the base and correlogram libraries [ 49].
A combined database will be created for analysis by merging data from the perinatal and qualitative database, intervention database and outcome assessment data base using the statistical package Stata 10.0.
Statistical analyses were performed on raw phenotypic data from each year using the R statistical base and pgirmess packages [ 50].
