From: A graphical method of cumulative differences between two subpopulations

Symbol | Meaning | Equation for the unweighted case | Equation for the case with weights |
---|---|---|---|

\(A_k\) | Abscissa for the cumulative graph in the case with weights | (Not applicable) | (16) |

\(C_k\) | Cumulative average difference between the subpopulations | (3) | (15) |

\(D_k\) | Average difference between the subpopulations | (1) and (2) | (1) and (2) |

\(\Delta _k\) | Expected slope of \(C_j\) from \(j = k\) to \(j = k+1\) | (6) | (20) |

G
| Kolmogorov-Smirnov statistic | (11) | (11) |

H
| Kuiper statistic | (12) | (12) |

\(R^j_k\) |
(Average) response for subpopulation j’s kth block—random dependent variable, outcome, or result
| (Step 4 within section “Unweighted sampling”) | (Readjusted in section “Weighted sampling”) |

\(S^j_k\) |
(Average) score for subpopulation j’s kth block—non-random independent variable
| (Step 4 within section “Unweighted sampling”) | (Readjusted in section “Weighted sampling”) |

\(\sigma\) | Scale of random fluctuations over the full range of scores | (13) | (21) |

\(T_k\) | Total weight for \(R^0_{k/2}\) or \(R^1_{(k-1)/2}\) | (Not applicable) | (14) |

\(W_k\) | Aggregated weight | (Not applicable) | (14) |
