grad pack

Dear List:

Does anyone know the difference between the "base" and the "standard" grad pack? 

I will be using ANCOVA and multiple regression to make predictions in my dissertation. 

Thanks so much,

Well, the site ( http://www.spss.com/software/statistics/academic/gradpack/) says that the 'standard' pack includes the base plus the "Advanced Statistics" and "Regression" modules.

I will be using ANCOVA and multiple regression to make predictions in my dissertation.

The base package may have all that you need; see the summary at http://www.spss.com/software/statistics/statistics-base/.

But see if you need any of these:
From Advanced Statistics ( http://www.spss.com/software/statistics/advanced-statistics/):

  • Generalized linear mixed models (GLMM) for use with hierarchical data
  • General linear models (GLM) and mixed models procedures
  • Generalized linear models (GENLIN), including widely used statistical models such as linear regression for normally distributed responses, logistic models for binary data, and loglinear models for count data.
  • GENLIN also offers many useful statistical models through its very general model formulation
  • Generalized estimating equations (GEE) procedures extend generalized linear models to accommodate correlated longitudinal data and clustered data
From Regression ( http://www.spss.com/software/statistics/regression/):

  • Multinomial logistic regression: Predict categorical outcomes with more than two categories
  • Binary logistic regression: Easily classify your data into two groups
  • Nonlinear regression and constrained nonlinear regression (CNLR): Estimate parameters of nonlinear models
  • Weighted least squares: Gives more weight to measurements within a series
  • Two-stage least squares: Helps control for correlations between predictor variables and error terms
  • Probit analysis: Evaluate the value of stimuli using a logit or probit transformation of the proportion responding
