r - 不同计算机上的回归输出不同

问题描述

我们在 Fedora 33 上使用 R 将广义线性模型拟合到一组数据。我们是 3 个人拥有完全相同的数据集、完全相同的操作系统 (Fedora 33)、完全相同的 R 版本和软件包版本。sessionInfo() 输出看起来也一样。这是当前的函数调用：

probitModel <- glm(Y ~ a + b + c +
                     d + e + f + g,
                   control=glm.control(maxit=100), 
                   start=startingval,
                   family = binomial(link = "probit"),
                   data = thisData)

需要注意的是，正常的“lm”拟合在比较时会产生完全相同的结果。关于“glm”的东西在不同的计算机上会产生少量的不同结果。最后，结果是一致的，因为我们都在同一台计算机上使用相同的数据得到相同的结果。只有当我们比较结果时才会出现问题。

我们检查了：

数据文件可以在这里找到。我们只是使用 load() 来设置数据，调用上面的函数，当输出应该相同时，我们得到的输出略有不同。

我对 sprintf("%.20f", probitModel$coefficients) 的结果：

"-2.87521118137333120401" "-0.29134882504319664642" "0.11641651353472137753"  "-0.00811350544106945529" "0.00939647781971938295"  "0.00000000889056301580"  "-0.00000000003021053820" "0.04553200818707187070"

另一台计算机的结果：
