Estimates of covariance parameters in raw beef meat samples between 0 and 7 days.

Parameter		Estimate	Wald Z	Sig.
Residual		0.134603	3.443	0.001
Day [subject = id]	Variance	0.006163	1.067	0.286
Residual		6.125832	3.464	0.001
Trial [subject = id]	Variance	37.76436	.	.

: this covariance parameter is redundant. The test statistic and confidence interval cannot be computed. Sig.: the p-value (associated with the correlation).
