The function evaluates the asymptotic test based on dS3 proposed in Kustosz, Mueller and Wendler (2016). It returns the test statistic and the decision. The main model is given by
Y_n = θ_0 + θ_1 Y_{n-1} + E_n .
1 | dS3_lin2_test(thetaN, alpha, y, exact = FALSE, cpow = 1, dS3)
|
thetaN |
Parameter defining the Null hypothesis H0: θ = θ^0. Thereby θ^0 is defined by the model. |
alpha |
Value in (0,1) defining the level of the test. |
y |
Observed series y=(y_0,...,y_N) for which the parameter test has to be executed. |
exact |
This switch allows the usage of an exact distribition of the test statistics using the sample size. |
cpow |
fixed and known power parameter for the Y_n = θ_1*Y_{n-1}^{cpow} + θ_0 model |
dS3 |
Here an evaluated dS3 statistic can be inserted instead of a vector y. Then just the test statistic is calculated and the test is evaluated directly. |
The theoretical details can be found in Kustosz, Mueller and Wendler (2016). The computational details are in Kustosz (2016).
TS |
Returns the value of the rescaled and centred test statistic. |
phi |
Retuns the test decision, phi = 1 means reject H0, and phi = 0 means do not reject H0. |
