Ich möchte einige Ergebnisse aus einer lmermod
Objekt extrahierenExtrahieren ergibt sich aus einem `lmermod` Objekt
require(lme4)
(fm1 <- lmer(Yield ~ 1|Batch, Dyestuff))
Dies erzeugt
Linear mixed model fit by REML ['lmerMod']
Formula: Yield ~ 1 | Batch
Data: Dyestuff
REML criterion at convergence: 319.6543
Random effects:
Groups Name Std.Dev.
Batch (Intercept) 42.00
Residual 49.51
Number of obs: 30, groups: Batch, 6
Fixed Effects:
(Intercept)
1527
Insbesondere würde Ich mag die Standard devations von extrahieren die 2 zufälligen Effekte, dh 42,00 und 49,51. Ich denke, es kann eine integrierte Methode, dies zu tun, aber ich konnte es nicht schnell finden, so dachte ich, soll ich in der Lage sein, es zu finden, indem str(fm1)
mit, die diese produziert:

Haben Sie versucht, 'Attribute (FM1)' verwenden? –
@DavidArenburg Ich hatte nicht, also habe ich gerade versucht und fand das 2. Element als 'fm1 @ devcomp $ cmp [10]', aber ich kann immer noch nicht die erste finden –
Die Klasse ist 'LmerMod' geschrieben –
