Webb7 apr. 2024 · 1 Answer Sorted by: 3 First of all, I'm not sure why you converted to ts as {ggplot2} can't use it and you didn't assign it back to dat in any case. Also in your data you have only one y value at each x value. Therefore it doesn't make sense to calculate any error or confidence interval. For example sd (1) returns NA.

WebbBootstrap confidence intervals for the actual cost of using a given nonparametric estimate of the optimal age replacement strategy are shown to have the claimed coverage probability. A numerical algorithm is given to obtain these confidence intervals in practice. The small sample behavior of these confidence intervals is illustrated by simulations. … WebbConfidence intervals As the MLEs do not exist in closed form, it is very difficult to obtain their exact distributions. Therefore, Abdel-Ghaly [ 109] suggested using the asymptotic confidence intervals based on the normal approximation. This procedure requires the inverse of the observed Fisher information matrix.
