• GENOVA (16.9 MB for PC and Mac)
    
  GENOVA is a ANSI FORTRAN computer program for univariate generalizability analyses with complete, balanced designs. It has both G study and D study capabilities. GENOVA was designed by R. L. Brennan and coded by J. E. Crick in the early 1980s. The file is large because the manual is a pdf version of a scanned file. 〔Fortran语言编写的，可以用来分析一元概化、完全、平衡设计问题，包括G研究和D研究〕
  
• urGENOVA (356 KB for PC and Mac)
    
  urGENOVA is an ANSI C computer program for the estimation of variance components for unbalanced random effects G study designs. The program does not have D study capabilities. urGENOVA was designed and coded by R. L. Brennan.（C语言编写的；分析一元概化的G研究，可进行非平衡、随机效应问题）
  
• mGENOVA (660 KB for PC and Mac)
  mGENOVA is an ANSI C computer program for multivariate generalizability analyses for a restricted class of designs. For these designs, the program has both G study and D study capabilities. mGENOVA was designed and coded by R. L. Brennan. （可进行多元概化分析）
  

在进行一元概化分析时，可以大胆使用GENOVA，它的功能还是很强大的，包括：随机或固定、交叉或嵌套以及混合设计，都可以进行。
在进行多元概化分析时，当然应该选用mGENOVA软件。但有些一元概化分析的问题不能在mGENOVA中进行，也就是说，mGENOVA并不完全包括GENOVA的功能。
另外，GENOVA和mGENOVA在编写代码的方式上还存在一定的差异。需要认真学习它们的mannual。
至于urGENOVA，只能进行方差分量的估计工作，但它能够进行非平衡设计的方差估计。这主要是看实际测量工作中是否会遇到非平衡设计的问题。
