Since the function appears in the following packages, you must 
load/decide which one you want:

Statistics`LinearRegression` ,
Statistics`MultiDescriptiveStatistics` , 
Statistics`MultiDiscreteDistributions` , 
Statistics`MultinormalDistribution` ,
[Statistics`Common` is NOT a package, do not load it directly]

Then you use either one of the commands

Needs["Statistics`LinearRegression`"]
Needs["Statistics`MultiDescriptiveStatistics`"]
Needs["Statistics`MultiDiscreteDistributions`"]
Needs["Statistics`MultinormalDistribution`"]
