1. Overview
2. Assumptions
3. Procedure
1. Overview
⑴ A method to test whether continuous measurement values having two values appear randomly without any pattern or trend
⑵ A run refers to a cluster starting and ending with the same measurement values
① Example : In a sequence like 1, 0, 0, 1, 0, 1, 1, 1, 0, 1, there are a total of 7 runs as 1/00/1/0/111/0/1
2. Assumptions
⑴ If the data is not binary, it should be converted to binary
⑵ Binarize using a criterion such as mean, median, mode, or a number defined by the user
3. Procedure
⑴ Step 1. Hypothesis Testing
① Null Hypothesis H0 : Continuous measurement values are random
② Alternative Hypothesis H1 : Continuous measurement values are not random
⑵ Step 2. Calculate Test Statistic
⑶ Step 3. Test Rejection Region
① If the p-value of z is less than (including equal to) the lower rejection region or greater than the upper rejection region, reject the null hypothesis
