> qls.fit
Call:
qls(formula = norm ~ time + x1, data = normal.1, id = normal.1$id,
time = normal.1$time, correlation = "exchangeable")
Coefficients:
(Intercept) time x1
1.16621 0.02031 0.95868
Degrees of Freedom: 240 Total (i.e. Null); 237 Residual
Scale Link: identity
Estimated Scale Parameters: [1] 0.7115
Correlation: Structure = exchangeable Link = identity
Estimated Correlation Parameters:
alpha:1
0.6869
Number of clusters: 80 Maximum cluster size: 3
我只想要提取qls.fit结果中的Estimated Correlation Parameters:
alpha:1
0.6869 ,不知怎么提取,希望大家帮帮我!
