Description

“对第二十四页论文中的图2.15（上图2.1）数据进行扒取，并对图片进行线性拟合（见上图2.2），得出图片线性拟合为y=0.1067xR2=01083，详细数据见附件。经验证，该数据的r方仅有0.1，证明生育数量与家暴发生率几乎无关。” 扒取后的线性拟合有常数项吗？图中的应该有。此外，相关性的存在应该由系数的显著性决定而不是R方。经济学数据信噪比极低，低R方是可以接受的。

Contributor guide

Research direction
Check whether the linear fit in Figure 2.15 includes a constant term. Also, assess the significance of the coefficient rather than relying solely on R squared for determining correlation.
