| Abstract: | In this paper we introduce certain numbers ,called collinearity indices, which are useful for dctecting near collinearities, The characteristics of these indices and the relation between the indices and the ill-conditioned numbers, and the multi-correlation coefficients are discussed. |

| Keywords: | collineatity ill-conditioned number Gram determinant linear regression |
