<p style="font-size: 16px; font-weight: normal">季节指数预测法，亦称“温斯特法”，是根据时间序列中的数据资料所呈现的季节变动规律性，对预测目标未来状况作出预测的方法。它首先建立预测模型来求得历史上各期的趋势值，然后用实际值除以趋势值来求出季节指数。若是有两个以上的波动周期，还需要求出相同时期的季节指数平均值，再用它去修正预测值。</p>

<p>假设某电商平台店铺主营夏季产品，如泳装、泳帽、泳镜、游泳圈等产品，这类产品具有明显的季节波动性，公司需要预测未来12个月的采购需求，请使用季节指数预测法完成任务。</p>
<p>
应用步骤
<br />
数据收集：收集历史采购数据，确保数据覆盖多个完整的季节周期。
<br />
数据预处理：清理数据，处理缺失值和异常值。
<br />
计算移动平均值：计算每个时间点的移动平均值，以平滑数据。
<br />
计算季节指数：通过将实际值除以移动平均值，计算每个月份的季节指数。
<br />
预测未来需求：利用季节指数和趋势数据预测未来的采购需求。

数据特征说明‌：
<br />
‌季节性规律‌
<br />
‌旺季（6-8月）‌：夏季需求高峰，采购量逐月攀升，7月达年度峰值（如2023年7月920件）；
<br />
‌淡季（12-2月）‌：冬季需求低迷，采购量显著低于其他月份（如2024年1月140件）。
<br />
</p>
<p>
年度增长趋势‌
<br />
每年采购量整体增长约 ‌5%-10%‌，符合行业稳定扩张特征（如2023年6月较2022年增长8.3%）；
<br />
冬季淡季增速较低（如2023年12月较2022年增长5.6%），夏季旺季增速较高（如2024年7月较2023年增长3.3%）。
<br />
</p>
<p>
过渡月份波动‌
<br />
春季（3-5月）和秋季（9-11月）为过渡期，采购量随气温变化逐步上升或下降（如4月采购量介于300-400件）；
<br />
9月后需求快速回落，反映季节性商品换季特征（如2022年9月采购量环比下降33%）

在电商产品投放测试中，熵值法可以用于评估不同投放策略或广告内容的效果。
<br />
<br />
通过收集多个反映投放效果的关键指标数据，如点击率、转化率、订单成交量等，利用熵值法计算各指标的权重，从而确定哪些指标对投放效果的影响更大。这有助于优化投放策略，提高广告效果和投资回报率。

<p>数据标准化：</p>
<p>
对于正向指标（点击量、曝光量、订单金额），我们采用极差标准化方法：
<br />
标准化公式为：Yij = (Xij - min(Xi)) / (max(Xi) - min(Xi)) 例如，某渠道的点击量极差标准化值=（某渠道点击量-点击量最小值）/（点击量最大值-点击量最小值）
<br />
对于负向指标（数值越低越好），标准化公式为：Yij = (max(Xi) - Xij) / (max(Xi) - min(Xi))。 例如，某渠道的广告费用极差标准化值=（广告费最大值-某渠道广告费用）/（广告费用最大值-广告费用最小值）
</p>
<p>数据标准化结果如下所示：</p>
