Вот снимок моих образцов MCMC:
, хотя он интуитивно понятен для поднабора по столбцам в виде samples[,1:15], очевидно, я хотел бы сдвинутьот жесткого кодирования номеров столбцов до формульного поднабора.
Например, вот как я (успешно) подмножество бета-версий:
p <- ncol(X.mod) # p=8
head(samples[, c(paste("beta[", 1:p, "]", sep = "")])
Проблема в том, что я не могу понять, как подмножество этих выборок в формальной форме путем итерации столбцаИмена, которые релевантны для моих y апостериорных распределений:
Вот что происходит, когда я пытаюсь установить подмножество n и p:
n <- nrow(X.mod) # n=52
p <- ncol(X.mod) # p=8
head(samples[, c(paste("y[",1:n,",", 1:p, "]", sep = ""))])
Подмножеству не удается выбрать все y, поскольку 1:n не повторяется для 1:p.
Как мне установить подмножество для всех из y[1:n,1:p] апостериорных распределений?
