Series overview:

• basic statistical characteristics, tests of randomness, outliers detection etc.
• normal distribution testing, histograms
• graphs of the series

Regression models:

• linear, polynomial regression
• multivariate linear regression

Adjusting data:

• replacing outliers, filling missing values, etc.
• various transformations, converting series into anomalies from a mean, etc.
• calculating differences/ratios of two series
• switching between monthly or seasonal and annual averages

Homogeneity testing:

• absolute homogeneity tests
• relative homogeneity tests ( Alexandersson‘s SNHT – various modifications, Bivariate test of Maronna and Yohai, Easterling‘s and Peterson‘s test, Vincent‘s MLR, and others ), creating reference series
• adjustment of inhomogeneities

Time series analysis:

• one series analysis (autocorrelations, power spectrum – MESA, dynamic MESA, etc.)
• two series analysis (coherency analysis, etc.)
• filtering the series (low-pass, band-pass, high-pass filters)

Database tools:

• data can be downloaded from central database straight to AnClim by means of LoadData software (“Download Wizard”). You just specify what to download, the rest is done by the software – converting data to a format suitable for AnClim, etc.

• Automation:
  • functions for automatized processing of selected functions (tests) for up to 1000 files (stations)
