Subclaims¶

q3 i3 ΔTS in the HMM correlated with TS in the CFA model (r = 0.78, p < 10−5), and βcap correlated with Cap (r = 0.45, p < 10−5) but not with TS (r = −0.01, p = 0.72). → Julia Ericson and Torkel Klingberg 2023

Correlational analysis linking HMM parameters fitted to daily training data with individual CFA parameters for the same children. The article reports "ΔTS in the HMM was signi ficantly correlated with TS in the CFA model (r = 0.78, p <1 0−5)"; the printed correlation r = 0.78 corresponds to a large effect.

"We found that ΔTS in the HMM was signi ficantly correlated with TS in the CFA model (r = 0.78, p <1 0−5, Table 1) and slightly correlated with Cap (r = 0.21, p <1 0−5)."
