How do I run a comparison using only one class twice?

I have a model:

public class Parameter
{
    [Key]
    public int paramID { get; set; }
    [Display(Name = "No.")]
    public int paramNo { get; set; }
    [Required]
    [Display(Name = "Title")]
    public string parameter { get; set; }
    [Display(Name = "Meaning")]
    public string description { get; set; }
    [Display(Name = "Synonym")]
    public string synonym { get; set; }
    public int catID { get; set; }
    public virtual ICollection<CompareParameter> CompareParameters { get; set; }
}

I need to add a model that compares all objects in the Parameter with each of the other objects in Parameter. So far I have this:

public class CompareParameter
{
    [Key]
    public int CompareID { get; set; }
    public int paramID1 { get; set; }
    public int paramID2 { get; set; }
    public virtual Parameter Parameters { get; set; }
    public virtual Parameter Parameters2 { get; set; }
}

Where paramID1 takes the key from Parameter and paramID2 does the same. Only it does not appear to be working at the moment.

Any ideas?

=== Update Question ===

With the two models I have given as examples, what should I do about CompareParameter to allow me to build a controller and a view that will have two dropdowns of the same class. The purpose of this is so that I can link it to another class with possible outcomes.

You should derive your Parameter class from Comparer and implement the comparison that way.
