How does the search work?
The search window will display any models or meta-analyses with the terms you selected in their title, description, or categories. You can also filter by models and meta-analyses with specified dependent or independent variables.
Searching models and meta-analyses.
What are categories?
Categories are a way to organize content on the site, and work like a hierachy of tags. Every model and meta-analysis can be placed within multiple categories, and the categories are organized within eachother. Categories are used both for searching and for browsing.
Hierarchy of tags.
What are models?
Models are parameter estimates. It can be a Dose-Response model, a Treatment-Control model, a Marginal Effect Distribution, or any other model which specifies for a set of independent variables the distribution of a dependent variable.
Models come from scientists and from scientific articles.
Attributes for the published article and parameters of a model.
What is the format for model information?
Although there are a number of ways to specify models, the most general is to upload a model file. There are a number of specifications. See the Model Formats Specifications for more information.
What kinds of graphs are available?
Here are some of the available graphs on the site, and where they're used:
For discrete probability models.
For categorical splines.
For dose-response curves.
For a single parameter, or pooled across models.
For a single parameter, or hierarchically simulated across models.
What are meta-analyses?
How can models be merged?
Models can be merged to produced "Pooled" estimates or "Hierarchical Normal" estimates. A pooled estimate is appropriate if all of the models are estimating the same thing. Hierarchical Normal estimates assume a hierarchical structure, whereby each model is an instance of a more general model, with an unknown dispersion between the models. This allows for "partial pooling".
What are scaffolds?
Scaffolds are a way to simplify the model input process. Every meta-analysis has a scaffold, and you can customize it to specify which fields should be hidden, pre-entered, and required. Then you can send it out to others to collect information.
What are distributions?
What are combinations?
