Testing True Long Memory Against Spurious Long Memory

Implements a test for distinguishing between true long memory and spurious long memory. Reference: Qu, Z. (2011). "A Test Against Spurious Long Memory." Journal of Business & Economic Statistics, 29(3), 423–438. .

SpuriousMemory

Test for the null hypothesis of fractional integration against spurious long memory

Overview

Detecting spurious long memory in time series using the method of Qu (2011). Distinguishes between true stationary long memory and spurious long memory caused by level shifts or smooth trends.

Example

library(SpuriousMemory)

# Data
data(RV5min)

result <- Longmemorytest(RV5min, demean = TRUE, alpha = 0.05)
