| | Features of NewMDSX V4.0 | Features of NewMDSX include: | Organised entirely within the Windows™environment; | | All of the original DOS programs have been modified: | some rarely used programs have been removed from the library (but are still available in the MS-DOS version); | | some new popular programs have been added; | | all programs have been given a substantial graphical component; | | data input and conversion have been simplified and systematised, and made maximally compatible with other MDS programs. |
|
| Several programs are designed for direct data input and analysis, rather than via measures of dis/similarity. These include: | Dominance pair-comparisons (MDPREF) | | Rankings/Ratings (MINI-RSA and MDPREF) | | Triadic data (TRISOSCAL, unique to NewMDSX) | | Free-sorting data (MDSORT) |
| | Constituent programs also include models which are similar to MDS (and often used in conjunction with it), such as Principal Components, Hierarchical Clustering and Conjoint Analysis | | DATA INPUT Input wizard, containing default values and Input matrix routine, gives tabbed screen display for input and output results allowing easy switching between the two. Fully text-editable windows. | | Data-matrix entry directly, inputting existing file, pasting from the clipboard and re-opening recently used file. | | Data-entry option to create one or more measures of dis/similarity (via WOMBATS utility - Work Out Measures Before Attempting To Scale) and save in variety of formats. | | Data for 2-way 1-mode matrix entry can be either a lower-triangle without diagonal, or a full matrix. | | Data matrices are assumed to be in free-format (space separated) but can still be input with a INPUT FORMAT statement for complex data formats. | | Ability to change data-matrix format for easing transfer between programs. This includes transferring between SPSS full-matrix input and NewMDSX , and since data are often interchanged between interactive PERMAP (with labelled lower-triangular and diagonal matrix input) and MINISSA, the option is provided for converting data matrix input (in either direction) |
| LABELS: Objects (usually stimuli, but where appropriate subjects/dat-sources) can be labelled for use in output and in graphics, either as an instruction in the Runscript, or in the process of data-input. | | GRAPHICS: Ability to produce 2- and 3-dimensional graphics of configurations, Shepard diagrams etc. which can be saved in bitmap (.bmp) or .jpg format for later insertion and editing. | | Final configurations can be submitted to a variety of (legitimate) similarity transforms, including: | reflection of axes | | orthogonal rotation - left, right; up/down and incremental change in each axis , together with | | Zoom in/out (uniform rescaling) and | | The entire configuration can be moved within the window. | | Each configuration has the fit value (e.g. stress) printed on it. |
| | For relevant vector models, objects (whether subjects or stimuli) can be represented as vectors from the origin rather than as points. | | After displaying, lines/contours can be drawn in the configuration, and points and regions can be labelled with text. | | Labelled points in output configurations can be shortened in length within the graphic editing procedure, and the size and font of the labels can be changed | | Clicking on an overlapping point will reveal its label | | within HICLUS, the option is given of producing graphical option in the form of a labelled horizontally defined dendogram | | For high (>=4 dimensions, an Andrews Plot is produced The Plot produces for each point a curve (which is a Fourier transform with dimensional co-ordinates as parameters), so that points close in high-dimensional space appear as similar wave-forms. | | NewMDSX COMMAND LANGUAGE: a RunScript is a set of sequential instructions (akin to SPSS syntax) formed in accord with the NewMDSX command language. Each command has a COMMAND component and an operand (or parameters) prefaced by one or more spaces. The operands no longer need to begin at position 16 , and input is assumed to be free-format. | | On the COMPUTE command, the RunScript is executed, but will stop at any line which has syntax errors. | | Home |
