WebThe platform uses “greedy nearest-neighbor matching” with a caliper of 0.1 pooled SDs and difference between propensity scores ≤0.1. Covariate balance between groups was assessed using standardized mean differences (SMDs). Any baseline characteristic with a SMD between cohorts <0.1 is considered well matched. 8. WebThe nearest-neighbor chain algorithm constructs a clustering in time proportional to the square of the number of points to be clustered. This is also proportional to the size of its input, when the input is provided in the form of an explicit distance matrix. The algorithm uses an amount of memory proportional to the number of points, when it ...
