Non-zero coefficients for the one SE nested cross-validated lasso model

Variable	Coefficient
unknown_1	2.48
public_1	1.62
private_1	1.43
perpetrator_syria	1.38
perpetrator_russia_syria	0.88
perpetrator_us_coalition	0.24
(Intercept)	0.11

Larger coefficients indicate that a variable stayed in the model for a longer time before being zeroed out by the penalisation and are thus more closely related to the outcome that healthcare infrastructure was attacked.
