SuperMix 將 Donald Hedeker 與 Robert Gibbons 開發的 4 個混合效應程式：MIXREG、MIXOR、MIXNO 和 MIXPREG 的功能結合了起來，構成了一個單獨的應用程式以便提高混合效應回歸模型的預測。


混合效應模型也就是通常所說的多層、分層，或者隨機效應模型。這些模型可以用於縱向資料的分析，其中每一個體都可以在各種不同場合中測量。他們還可以在聚類資料上使用，例如診所裏的病人。


SSI 在“第二階段小企業創新研究計畫，N44MH32056 合約”下，開發了 SuperMix，並發佈於 2008 年 9 月。SuperMix 可以匹配使用嵌套數據的連續、計數、序數、標稱和生存輸出變數的模型，允許最多三層嵌套數據。


關鍵特性列表如下：


1.易用的圖形使用者介面： 導入資料到 SuperMix 表格，然後用功能表和對話方塊建立新的模型。


2.用於自動相關殘差的連續輸出變數的混合效應模型。


3.用於序數回歸分析（包括非對稱奇數模型和縮放效應）的混合效應模型。


4.用於泊松回歸分析的混合效應模型。


5.用於序數邏輯回歸分析的混合效應模型。


6.用於分組時間生存分析的混合效應模型。


7.為2層和3層嵌套資料設計的模型。


8.報告品質的圖像。


SuperMix combines the functionality of four mixed-effects programs, MIXREG, MIXOR, MIXNO, and MIXPREG, developed by Donald Hedeker and Robert Gibbons into a single application to provide estimates for mixed-effects regression models.


Mixed-effects models are also known as multilevel, hierarchical, or random-effects models. These models can be used for the analysis of longitudinal data, where each individual may be measured at a different number of occasions. They can also be used for clustered data, such as for patients within clinics.


SuperMix has been developed by SSI under an SBIR Phase II contract N44MH32056, and has been released in September 2008. SuperMix will fit models with continuous, count, ordinal, nominal, and survival outcome variables with nested data, allowing for up to three levels of nesting. Key features are listed below.


1.Easy to use graphical user interface: import data into the SuperMix spreadsheet, then build new models using menus and dialog boxes.


2.Mixed-effects models for continuous outcome variables with auto-correlated residuals.


3.Mixed-effects models for ordinal regression analysis, including non-proportional odds models and scaling effects.


4.Mixed-effects models for Poisson regression analysis.


5.Mixed-effects models for nominal logistic regression analysis.


6.Mixed-effects models for grouped-time survival analysis.


7.Two- and three-level models allowing for nested designs.


8.Presentation quality graphics.
