GAMLSS错误:参数µ的工作矢量或权重中有NA

Question

对于gamlss函数，我得到了以下错误ERROR : NA's in the working vector or weights for parameter mu：fit <- gamlss::gamlss(x ~ y, sigma.formula = ~ y, data = d, family = GA)

其中d是包含x和y的数据帧

x = 17.83961 29.73269 14.15842 15.00793 35.53764 13.53545 17.13169 35.67923 14.68229 10.59050 13.73367 26.58952 21.33674 28.60002 36.24556 22.00219 30.2990326.50457 28.17526 41.05943 19.22714 37.09507 24.32417 21.29427 23.72952 23.72952 18.37763

此错误的原因是什么？

Answer 1

也许这与数据有关。如果你交换x和y，一个模型就会出来：

fit <- gamlss(y ~ x, sigma.formula = ~ x, data = d, family = GA)
