Linearly rescales estimated document positions on the basis of two control points.
rescale(object, ident = c(1, -1, 10, 1))
| object | fitted wordfish or wordscores object |
|---|---|
| ident | two documents indexes and and their desired new positions |
A data frame containing the rescaled document positions with standard errors if available.
The rescaled positions set document with index ident[1] to position ident[2] and docuemnt with index ident[3] to position ident[4]. The fitted model passed as the first argument is not affected.
