A Distributed Framework for Predictive Analytics Using Big Data and MapReduce Parallel Programming

Algorithm 2

Reduce function of MapReduce-I

	Function REDUCE-1(MAP-I output)
	read < Dataset id, (intercept, coefficients[]> from HDFS
	for i = 1 to s partitions
	sum_intercept+ = intercept
	end for
	for i = 1 to s partitions
	for j = 1 to n attributes
	sum_coefficients[]+ = coefficients[]
	end for
	end for
	compute avg_intercept, avg_coefficients[]
	construct a learned MR-MLR model
	output < MR-MLR model>
	end
