Abstract : This document considers a linear regression model, where (x sub i) is a sequence of experimental points, i. e., known pvectors, (e sub i) is a sequence of independent random errors, with med(e sub i) =0,i= 1,2....Define the minimum L1 norm estimate of (alpha, beta)', by (alpha, beta)', to be chosen such that under quite general conditions on (x sub i) and (e sub i), the strong consistency of the minimum L1 norm estimate is established. Further, under an additional condition on (x sub i), it is also proved that for any given epsilon 0, there exist constant C O not depending on n.
