Data from thermal tolerance trials

These are the data from thermal tolerance trials from putting sea urchin embryos into vials in a thermal gradient. Development was scored after 2, 10 or 20 hours. Tolerances where tested for the upper and lower thermal limit. Upper thermal limit trials are "heatblocks" and lower thermal limits are "coldblocks". The data are formatted for logistic regression analysis, so each vial has two row entries, one with the the number of successes for each category and one with the number of failures for each category.本数据集来源于热耐受性试验：将海胆胚胎置于热梯度环境的试管中开展培养，分别于2小时、10小时及20小时后对胚胎发育状态进行评分。本次试验测定了受试对象的上下热耐受极限，其中上热耐受极限试验命名为热阻块（heatblocks），下热耐受极限试验命名为冷阻块（coldblocks）。本数据集已针对逻辑回归分析完成格式标准化：每个试管对应两行数据条目，一行记录各分类下的成功样本数，另一行记录对应分类下的失败样本数。
