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.
Extra wide double fold bias tape being sewn as a binding for a decorative quilt. In sewing, binding is used as both a noun and a verb to refer to finishing a seam or hem of a garment, usually by rolling or pressing then stitching on an edging or trim. [1]
HTTP Live Streaming (also known as HLS) is an HTTP-based adaptive bitrate streaming communications protocol developed by Apple Inc. and released in 2009. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers.
Hem detail with inscriptions, Saint-John in Crucifixion, Ferrara, by Vicino da Ferrara (1469–70). A hem in sewing is a garment finishing method, where the edge of a piece of cloth is folded and sewn to prevent unravelling of the fabric and to adjust the length of the piece in garments, such as at the end of the sleeve or the bottom of the garment.
The Heckman correction is a statistical technique to correct bias from non-randomly selected samples or otherwise incidentally truncated dependent variables, a pervasive issue in quantitative social sciences when using observational data. [1]
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:
The mean difference is the estimated bias, and the SD of the differences measures the random fluctuations around this mean. If the mean value of the difference differs significantly from 0 on the basis of a 1-sample t-test, this indicates the presence of fixed bias. If there is a consistent bias, it can be adjusted for by subtracting the mean ...
