Xcalibre 4 提供了多個超越Xcalibre 1.1的特色：

1. Superior output: save time by utilizing the rich text file (RTF) format prepared as a formal report with embedded tables and graphics, rather than having to build your own report manually. Graphics include the item response function (IRF), the item information function (IIF), the test information function (TIF), and conditional standard error of measurement (CSEM), and numerous frequency distributions. In addition, you can also overlay the empirical fit line with the IRF.

2. More models: Dichotomous models include the 3PL, 2PL, 1PL, and Rasch models. Five polytomous models (below) are also included, plus you are allowed to mix the models for mixed-format tests.

3. Screening: automatically screen out items with unacceptable classical statistics before performing the IRT item parameter calibration.

4. Custom flagging: customize item flagging rules by specifying acceptable ranges and your own flag labels.

5. Produces spreadsheets: easily import results into test development software because statistics are saved as a comma-separated value (CSV) format, which is also able to be easily manipulated (sorted, highlighted, etc.) in spreadsheet software.

6. More theta estimates: can now be produced for multiple domains as well as the full test.

7. Mastery testing: automatically implement cutscores for criterion-referenced tests.

8. More items: analyze up to 1,200 items at once.

9. Pilot/pretest items: compute classical statistics for pretest (pilot or unscored) items to be used for item evaluation.

10. Multiple runs (batch): utilize a “batch” type of capability, to allow you to run multiple data sets without having to use the graphic user interface for each run.

11. Differential item functioning (DIF): evaluate DIF with the Mantel-Haenszel approach.
 

IRT模型

Xcalibre調整下列IRT模型：

• 3-parameter dichotomous model, ideal for multiple choice data
• 2-parameter dichotomous model, ideal for personality data
• 1-parameter dichotomous model, with equivalent item discriminations
• Rasch dichotomous model, scaled to items rather than people
• Rasch rating scale model (RRSM, or RSM)
• Rasch partial credit model (RPCM, or PCM)
• Generalized rating scale model (GRSM)
• Generalized partial credit model (GPCM)
• Samejima's Graded response model (SGRM, or GRM)
   

Moreover, you are allowed to utilize both a dichotomous and polytomous model at once. For example, if your test has 100 multiple choice questions and 5 open response questions scored with partial credit, you can calibrate all items easily onto a common scale. Because no programming code is involved (point-and-click only), even researchers new to IRT can easily produce such powerful analyses.
 

最近增加(2011年8月)

• Mantel-Haenszel differential item functioning (DIF)
• Automatically calculate scaled scores for examinees
• Items with insufficient response frequencies now excluded
• Statistics, scores, and test information files are now optional
• Option for comma-delimited or tab-delimited output
• Meaningful labels for domains provides easier to read output
• Skew, Q1, Median, Q3, IQR now computed for all scores
• -2LL provided to compare fit of competing models
• Item control and item status tables provided in report
• Item-person map plots the distribution of b and θ together
• Item parameter and flag table presents the most important
   

使用Xcalibre 4

Xcalibre 4 is designed to be user-friendly, with a straightforward graphical user interface that involves no DOS-style command code. All options are specified by radio buttons and check boxes; once you have all of your specifications set, simply hit the "Run" button!


Xcalibre 4 produces top-of-the-line reports designed to make it easier to apply IRT. Instead of oversimplified ASCII-text files, it produces a detailed document with colored headings, embedded figures and tables, and explanations. All statistics are also saved as a CSV file to allow you to work in a spreadsheet and easily upload to test development systems such asFastTEST Web . In addition to the detailed page show below, which is produced for every test item,Xcalibre 4 provides a wide range of test-level output for the overall test as well as each domain (content area):

• Test information function (TIF)
• Conditional standard error of measurement (CSEM)
• Test response function (TRF)
• Grouped frequency distributions of theta estimates
• Coefficient alpha
• Summary statistics of item parameters, raw scores, and theta estimates.
• Overall grouped frequency distributions of item parameters

更新訊息

Iteman™ 4 offers several substantial improvements from the previous version, ITEMAN™ 3.6:

1. The most important advantage is the addition of graphics. It is now possible to produce an item quantile plot for each item.
2. Iteman™ 4 is able to handle pretest (trial or unscored) items, items that are not included in the final score but where statistics are still desired.
3. More statistics are calculated, including the alpha (KR-20) reliability coefficient with each item deleted, and subgroup P (proportion correct) statistics.
4. Instead of simple ASCII text files, the output is now rich text file (RTF) format laid out as a formal report, and also in a comma-separated value (CSV) format that is able to be manipulated (sorted, highlighted, etc.) in spreadsheet software. It additionally produces a CSV file of examinee scores and subscores.
5. Scaled scoring can be applied, so that Iteman 4 can be used to score sets of examinees in more testing programs and provide scores on any linearly transformed scale.
6. Items can be analyzed relative to an external score rather than the total score on a test.
7. The maximum number of items that can be analyzed has been increased to 10,000, with no limit on the number of examinees.
8. A “batch” type of capability, using a “multiple runs file” has been added to allow you to run multiple data sets without having to use the graphic user interface for each run.

Iteman 4 can analyze both dichotomous (correct/incorrect) and polytomous (ratign scale or partial credit) data, including tests that are a mix of both item types.

What does Iteman™ 4 look like?
Using Iteman 4 is straightforward: simply name the relevant files and then utilize the friendly interface to specify options for your results. One tab of the options is devoted to scoring... 

The program produces summary output regarding the examinee scores, including reliability analysis, analysis of domains (content areas), and frequency distributions. 

However, the majority of the report is item-by-item results, presented in detailed tables and a quantile plot for each item. Simply paste in item texts, and you have a comprensive report ready for item reviewers! 

Iteman has been the world’s most used item and test analysis software since its release in the early 1980s.Iteman 4 sets a new standard for analyzing test data.
