WebGiven two groups, such as a treatment and a control group, and a method of creating a treatment-by-control discrepancy matrix indicating desirability and permissibility of potential matches (or optionally an already created such discrepancy matrix), create optimal full matches of members of the groups. Optionally, incorporate restrictions on matched sets' … WebDistance based bipartite matching using the RELAX-IV minimum cost flow solver, oriented to matching of treatment and control groups in observational studies. Routines are provided to generate distances from generalised linear models (propensity score matching), formulas giving variables on which to limit matched distances, stratified or exact matching … WebSPSS R plugin and PS Matching plugin. 色环插件PS色环插件. 色环其实就是在彩色光谱中所见的长条形的色彩序列,只是将首尾连接在一起,使红色连接到另一端的紫色,色环通常包括12种不同的颜色。 how a family is formed
