Regressions in dog Live Release Rate changes up to 7.5 points for government-related shelters, 2016-2024

The related research paper will be indicated here when DOI is available. A specific feature of this dataset is that ∆LRR mean-centered by period is limited to absolute values less than or equal to 7.5 points.Abbreviations:LRR = Live Release RateFile name prefix:Descriptive_ = descriptive statistics of baseline value and ∆ of ratio being studied (Table 1 in paper)Avg_ = descriptive statistics of field changes (Table 2 in paper)RegInfo_ = number of observations and residual dof of regression (given in text in paper)RegChange_ = the main regression result (Tables 3 & 4 in paper, see suffix information below)ByMonth_ = data counts by period (not given in paper, but brief instance in text)ChangeTime_ = regression result for the period categorical covariate, not of interest (not given in paper)File name suffix with letter number. The letter "f" signifies the fraction formulation and the letter "a" the count formulation in the paper. The number is the months included in each baseline or follow-up window (12 for calendar year windows).File name middle portion consists of two terms. They are the numerator and denominator of the ratio being studied. For LRR, they are "live" and "outcome" because "live" signifies (in the paper) the sum of all live outcomes and "outcome" signifies the sum of all outcomes.

当获取到数字对象标识符（DOI）后，相关研究论文将在此处标注。本数据集的一项显著特征为：经周期中心化处理后的ΔLRR的绝对值被限定在7.5个百分点以内。

缩写说明：LRR（Live Release Rate）指活产率。

文件名前缀规则如下：
- Descriptive_：代表研究中基线值与目标比值变化量的描述性统计（对应论文中的表1）；
- Avg_：代表各字段变化情况的描述性统计（对应论文中的表2）；
- RegInfo_：包含回归分析的观测值数量与残差自由度（详见论文正文）；
- RegChange_：核心回归结果（对应论文中的表3与表4，详见下文后缀说明）；
- ByMonth_：按周期统计的数据计数（论文未完整提供该类文件，仅在正文中有简要示例）；
- ChangeTime_：针对周期分类协变量的回归结果，并非本研究的关注对象（论文未提供该类文件）。

文件名后缀由字母与数字组合而成：其中字母"f"代表论文中采用的分数形式设定，字母"a"代表计数形式设定；后缀中的数字代表每个基线或随访窗口所包含的月份数（例如数字12代表以日历年为单位的窗口）。

文件名中间部分包含两个字段，分别为所研究比值的分子与分母。以LRR为例，二者分别为"live"与"outcome"：在论文中，"live"指代所有活产结局的总和，"outcome"指代所有结局的总和。
