MakeConfusionMatrix: Making a Confusion Matrix.

In Buddle: A Deep Learning for Statistical Classification and Regression Analysis with Random Effects

Description

Create a confusion matrix from two vectors of labels: predicted label obtained from FetchBuddle() as a result of prediction and true label of a test set.

Usage

MakeConfusionMatrix(predicted.label, true.label, Label)

Arguments

predicted.label	a vector of predicted labels.
true.label	a vector of true labels.
Label	a vector of all possible values or levels which a label can take.

Value

An r-by-r confusion matrix where r is the length of Label.

Examples

data(iris)

Label = c("setosa", "versicolor", "virginica")

predicted.label = c("setosa", "setosa",    "virginica", "setosa", "versicolor", "versicolor")
true.label      = c("setosa", "virginica", "versicolor","setosa", "versicolor", "virginica")

confusion.matrix = MakeConfusionMatrix(predicted.label, true.label, Label)
precision = GetPrecision(confusion.matrix)
