$\begingroup$ thank you for your answer and pointing out my mistake on frequency to set up at 7.Also, order of differencing also It helped me to find the seasonal differencing. I checked for stationary or non stationary with Dickey-Fuller test adf.test(cooltemp, alternative = "stationary") and the result of p-value was smaller than 0.01, on the other hand, i checked adf.test(cooltemp Dickey-Fuller Test/Augmented Dickey-Fuller (ADF) Test: This is a statistical test that checks for the presence of a unit root in the time series. If the test indicates that there is no unit root I mistook the p value for ADF test for the KPSS one. auto.arima only uses KPSS by default to specify d. The fact that salests produces a p value of 0.1 would mean that d should be zero (based on the source code). So, probably salests does not end up in that part of the auto.arima code. KPSS: The timeseries fails to reject the null hypothesis of stationarity (wtf? how can this timeseries be stationary if it clearly has a tendency upwards?) ADF: Can't reject tau (at 1%) and therefore there is a unit root, reject phi2 and therefore there must be drift, trend or both. ADF Test for Stationarity. The ADF test is one of the most popular statistical tests. It can be used to help us understand whether the time series is stationary or not. After cross-check ADF test and KPSS test. We can conclude that the three time series data we have here are not stationary. We will transform the time series to be stationary Now I check stationarity with the ADF and the KPSS tests, and both seem to suggest stationarity. ADF: adf.test(Data) Augmented Dicke y-Fuller Test data: Data Dickey-Fuller = -3.4722, Lag order = 7, p-value = 0.04498 alternative hypothesis: stationary ADF and KPSS test for non seasonal unit roots. Since your seasonality is strong, take the So, this means that, asymptotically, temporal aggregation or selective sampling have no consequences in terms of size distortion, or loss of power, for the ADF, Phillips-Perron test, or Hall's (1994) IV-based unit root test.The same is true for several other related tests. Pierce and Snell also show that even in finite samples, this result holds quite well; and it also applies to tests of non kpss_stat float. The KPSS test statistic. p_value float. The p-value of the test. The p-value is interpolated from Table 1 in Kwiatkowski et al. (1992), and a boundary point is returned if the test statistic is outside the table of critical values, that is, if the p-value is outside the interval (0.01, 0.1). lags int.
