WebStatistical Term- Bias. Bias is a statistical term which means a systematic deviation from the actual value. It is a sampling procedure that may show some serious problems for the researcher as a mere increase cannot reduce it in sample size.

We saw this in the previous formula. The larger λ is, the more the projection is shrunk in the direction of u j. Coordinates with respect to the principal components with a smaller variance are shrunk more. Let's take a look at this geometrically. medrol dose pack for osteoarthritis
