Treatment groups were compared using analysis of variance, paired t test or Wilcoxon signed rank test, depending on data distribution, using the JMP software (SAS, Cary, NC).
The plasma/serum levels measured in patients and controls were compared by Student's t-test or Mann-Whitney U test, depending on data distribution, using Prism software.
Pearson or Spearman correlation depending on data distribution were used to assess bivariate relationships between 25(OH D and fasting glucose, fasting insulin, HbA1c, insulin sensitivity, first-phase insulin, and DI.
Pearson or Spearman correlation, depending on data distribution, was used to assess bivariate relationships between 25(OH D and clamp-derived measures (insulin sensitivity, first-phase insulin, and DI).
Appropriate algorithm for choice of which linear model should now be used depending on data is very similar to fault detection and isolation one.
Level 1 (project specific), Level 2 (region specific), or Level 3 (default) inputs were used, depending on data availability.
For repeated measures outcomes, paired samples t-tests or Wilcoxon signed rank tests were used, depending on data characteristics.
Depending on data requirements, models will be developed using fixed-entry binary logistic regression, multilevel modelling and multiply imputed data sets, to compare outputs based on statistical technique.
You'll pay a monthly line access fee and then, depending on your data use, about $30 a month for 4GB of data.
Optimal damping parameter probably depends on data amount used (number of ships) and ratios of tsunami signals to background noises.
