The following sample autocorrelation estimates are obtained using 200 data points: | Lag | 1 | 2 | 3 | |-----|-----|------|------| | Coefficient | 0.3 | -0.15 | -0.10 | Compute the value of the Box-Pierce Q-statistic. | Financial Risk Manager Part 1 Quiz - LeetQuiz

Explanation:

The Box-Pierce Q-statistic is given by:

$Q_{BP} = n \sum \rho_k^2$

Where $n$ is the sample size and $\rho$ represents the autocorrelations.

Therefore, $Q_{BP} = 200(0.3^2 + (-0.15)^2 + (-0.10)^2) = 24.5$

Calculation breakdown:

$0.3^2 = 0.09$
$(-0.15)^2 = 0.0225$
$(-0.10)^2 = 0.01$
Sum = 0.09 + 0.0225 + 0.01 = 0.1225
$Q_{BP} = 200 \times 0.1225 = 24.5$
