Description

Given two rows and a fitted heuristic, returns the heuristic's predicted probability that row1's criterion will be greater than row2's.

Usage

1
predictPairProb(row1, row2, object)

Arguments

row1

The first row of cues (will apply cols_to_fit for you, based on object).

row2

The second row (will apply cols_to_fit for you, based on object).

object

The fitted heuristic, e.g. a fitted ttbModel or logRegModel. (More technically, it's any object that implements predictProbInternal.)

Value

A double from 0 to 1, representing the probability that row1's criterion is greater than row2's criterion. 0.5 could be a guess or tie.

See Also

rowPairApply to get predictions for all row pairs of a matrix or data.frame.

predictPairProb(oneRow(train_matrix, 1), oneRow(train_matrix, 2), lreg)
