mv.shape.est {MNM} | R Documentation |
Shape matrix estimates using different score functions.
mv.shape.est(X, score = "identity", estimate = "outer", location = NULL, na.action = na.fail, ...)
X |
a numeric data frame or matrix. |
score |
score to be used. Can be either "identity" , "sign" , "symmsign" or "rank" . |
estimate |
can be "outer" or "inner" . |
location |
If NULL the location vector is estimated. Alternatively a numeric p vector of location. |
na.action |
a function which indicates what should happen when the data contain 'NA's. Default is to fail. |
... |
further arguments passed to or from other methods. |
This functions returns different shape matrices depending on the score function chosen. For details see chapter 9 of the MNM book.
