Bradford 系数有什么用？What is the Bradford Factor used for?
一些雇主用它衡量缺勤模式：B = S² × D，S 是缺勤次数，D 是总天数，所以多次短期缺勤的分数远高于一次长期缺勤（10 次各 1 天为 1000 分，1 次 10 天只有 10 分）。它不是健康诊断。Some employers use it to spot absence patterns: B = S² × D, where S is the number of spells and D the total days, so frequent short absences score far higher than one long one (10 one-day spells = 1,000; one 10-day spell = 10). It is not a health diagnosis.
能举个计算实例吗？Can you show a worked example?
例如在「Bradford 因子」中填 病假次数 = 3，总天数 = 10，结果区显示：Bradford：90For example, entering Spells = 3, Total days = 10 in the Bradford Factor gives: Bradford: 90
哪些输入会被检查？Which inputs are validated?
「Bradford 因子」会检查这些输入——「病假次数」：必须填写；「总天数」：必须填写，不能为负数，须为整数；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Bradford Factor checks its inputs — "Spells": required; "Total days": required, cannot be negative, must be a whole number; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.
有哪些选项可以调整？What options can I adjust?
「Bradford 因子」的设置：「病假次数」默认 3；「总天数」默认 10。每次生成结果都按当前设置处理。Settings in the Bradford Factor — "Spells" default 3; "Total days" default 10. The result always uses the current settings.
结果可以代替医生的建议吗？Can this replace medical advice?
不能。「Bradford 因子」基于常用公式给出估算，个体差异较大，如有健康问题请咨询医生或专业人士。No. The Bradford Factor gives estimates from common formulas; individuals differ, so consult a doctor or professional for health decisions.
