utilities

Package (GS_LV/src/main/java/org/gsusers/gsmv/utilities) contains a collection of ten smaller objects that provide specific functions to various other parts of G_String.

'About.java' is a short function to display 'AboutXX.txt' files.

'CompConstrct.java' constructs the various facet combinations for each of the configurations that has a separate variance component. It is used in 'SynthGroups.java'.

'constructSimulation,java' assembles the synthetic data file from the random configuration components. It is used in 'SynthGroups.java'].

'FacetModView.java' provides the JavaFX snippet allowing to change the facet levels for D-Studies in 'AnaGroups.java'.

'Factor.java' is used for synthesis. It calculates the total number of possible states, each factor making up a configuration, can assume for all possible indices of its constituent facets. It is used in 'SampleSizeTree.java'.

'Filer.java' is an I/O utility, wherever G_String performs file input or output.

'Lehmer.java' is a small routine that signs synthetic data sets, so they can be distinguished from genuine experimental data. It is used in 'SynthGroups.java'.

'Normal.java' is a small routine that generates an array of Double numbers, distributed normally with a given mean and standard deviation. Such arrays are needed to generate a synthetic data set.

'SampleSizeView.java' is a specialized text field for entering sample size values.

'TextStack.java' a simple markup text rendering engine for help screens.

'VarianceComponent.java' uses Brennan's rules when calculating , σ²(τ), σ²(δ), and σ²(Δ) .
