error_calculation: Error calculation for integrated model

In IntegratedMRF: Integrated Prediction using Uni-Variate and Multivariate Random Forests

Description

Combines Prediction from different data subtypes through Least Square Regression and computes Mean Absolute Error, Mean Square Error and Pearson Correlation Coefficient between Integrated Prediction and Original Output feature.

Usage

error_calculation(final_pred, final_actual)

Arguments

final_pred	A n x p matrix of predicted features, where n is the number of samples and p is the number of data subtypes with prediction
final_actual	A n x 1 vector of original output responses

Details

If final_pred is a vector, it refers to the prediction result for one subtype of dataset and this function will return Mean Absolute Error, Mean Square Error and Pearson Correlation Coefficient between predicted and Original Output response. If final_pred is a matrix containing prediction results for more than one subtype of dataset, Least Square Regression will be used to calculate the weights for combining the predictions and generate an integrated prediction of size n x 1. Subsequently, Mean Absolute Error, Mean Square Error and Pearson Correlation Coefficient between Integrated Prediction and Original Output responses are calculated.

Value

List with the following components:

Integrated Prediction	Integrated Prediction based on combining predictions from data subtypes using Least Square Regression
error_mae	Mean Absolute Error between Integrated Prediction and Original Output Responses
error_mse	Mean Square Error between Integrated Prediction and Original Output Responses
error_corr	Pearson Correlation Coefficient between Integrated Prediction and Original Output Responses
