Fit a DFA with different number of trends and return the leave one out (LOO) value as calculated by the loo package.

find_dfa_trends(
y = y,
kmin = 1,
kmax = 5,
iter = 2000,
thin = 1,
compare_normal = FALSE,
convergence_threshold = 1.05,
variance = c("equal", "unequal"),
...
)

## Arguments

y A matrix of data to fit. Columns represent time element. Minimum number of trends, defaults to 1. Maximum number of trends, defaults to 5. Iterations when sampling from each Stan model, defaults to 2000. Thinning rate when sampling from each Stan model, defaults to 1. If TRUE, does model selection comparison of Normal vs. Student-t errors The maximum allowed value of Rhat to determine convergence of parameters Vector of variance arguments for searching over large groups of models. Can be either or both of ("equal","unequal") Other arguments to pass to fit_dfa()
