TABLE 1.

Hypothesis testing using Bootstrap to compare compositional lasso (CL) with random forests (RF) based on Stability or prediction metric (MSE) using two simulation scenarios (*indicate statistically significant)

Example (N = 100 & P = 1000)(Continuous)	Estimated mean difference (CL‐RF) in Stability index with 95% CI	Estimated mean difference (CL‐RF) in MSE with 95% CI
Toeplitz 0.5	0.22 (0.19, 0.28)*	0.23 (‐0.62, 1.36)
Block 0.5	0.23 (0.17, 0.29)*	0.44 (‐0.27, 1.57)
