Extra-wide double-fold bias tape being sewn as a binding on a decorative quilt An example of single-fold bias tape An example of double-fold bias tape Commercial bias binding foot fed with bias binding, producing bias binding tape. Bias tape or bias binding is a narrow strip of fabric, typically plain weave, cut on the bias.
Under simple random sampling the bias is of the order O( n −1). An upper bound on the relative bias of the estimate is provided by the coefficient of variation (the ratio of the standard deviation to the mean). [2] Under simple random sampling the relative bias is O( n −1/2).
Bias is a distinct concept from consistency: consistent estimators converge in probability to the true value of the parameter, but may be biased or unbiased (see bias versus consistency for more). All else being equal, an unbiased estimator is preferable to a biased estimator, although in practice, biased estimators (with generally small bias ...
The bias is a trivial calculation, but the variance of ¯ is more involved since the jackknife replicates are not independent. For the special case of the mean, one can show explicitly that the jackknife estimate equals the usual estimate:
Bias The bias direction of a piece of woven fabric, usually referred to simply as "the bias", is at 45 degrees to its warp and weft threads. Every piece of woven fabric has two biases, perpendicular to each other. Non-woven fabrics such as felt or interfacing do not have a bias. bias tape Bias tape or bias binding is a narrow strip of fabric ...
