An employee at Falcon Security is studying an analyst of data regarding the occurrence of problems and failures with its drones camera. Based on the analysis, the employee may schedule maintenance on the equipment Falcon Security is using the analysis to decision making.
Answer:
a) H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
b) t stat = -0.064
c) We will reject the Null hypothesis and the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise
Explanation:
<u>a) stating the null and alternative hypothesis</u>
H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
<u>b) performing the test </u>
critical value = -2.88
T stat = coefficient / std error
= -0.02 / 0.31 = -0.064
c) From the test, the value of T stat > critical value we will reject the Null hypothesis hence the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise
<span>Gregory's rules of thumb, which he uses in decision making, are known as heuristics.
Heuristic refers to a solution to a problem - it is something you employ in order to achieve the best results possible. These methods you use may not be perfect, but they will help you do what you intended to do properly.
