Description

Tests on a time series

Usage

tests(
  y,
  parts = 1/3,
  nCoef = min(25, length(x)/4),
  nPar = 0,
  s = frequency(y),
  avoid = 16
)

Arguments

y

a vector, ts or tsibble object

parts

proportion of sample to include in ratio of variances test

nCoef

number of autocorrelation coefficients to estimate

nPar

number of parameters in a model if y is a residual

s

seasonal period, number of observations per year

avoid

number of observations to avoid at beginning of sample to eliminate initial effects

Details
