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

Multiple tests on a time series, including summary statistics, autocorrelation, Gaussianity and heteroskedasticity,
