report(both.model.glm)

We fitted a linear model (estimated using ML) to predict IPSyn13 with year and mode
 (formula: IPSyn13 ~ year + mode). The model's explanatory power is substantial (R2 =
0.29). The model's intercept, corresponding to year = 1 and mode = spoken
, is at 52.42 (95% CI [50.83, 54.01], t(390) = 64.56, p < .001). Within this model:

  - The effect of year [2] is statistically significant and positive (beta = 6.35, 95% CI
[4.32, 8.38], t(390) = 6.14, p < .001; Std. beta = 0.64, 95% CI [0.44, 0.85])
  - The effect of year [3] is statistically significant and positive (beta = 9.57, 95% CI
[7.56, 11.58], t(390) = 9.34, p < .001; Std. beta = 0.97, 95% CI [0.76, 1.17])
  - The effect of mode [written] is statistically significant and negative (beta = -6.80,
95% CI [-8.47, -5.13], t(390) = -7.98, p < .001; Std. beta = -0.69, 95% CI [-0.85,
-0.52])

Standardized parameters were obtained by fitting the model on a standardized version of
the dataset. 95% Confidence Intervals (CIs) and p-values were computed using a Wald
t-distribution approximation.

簡潔にしたい場合は、summary()する

report(t.best.model2) %>% summary()

We fitted a poisson mixed model to predict score with timing and learning. The model included ID as random effects.
The model's total explanatory power is weak (conditional R2 = 0.10) and the part related to the fixed effects alone
(marginal R2) is of 0.02. The model's intercept is at 1.45 (95% CI [1.39, 1.52]). Within this model:

  - The effect of timing [2] is statistically significant and positive (beta = 0.16, 95% CI [0.11, 0.22], p < .001,
Std. beta = 0.16)
  - The effect of timing [3] is statistically significant and positive (beta = 0.07, 95% CI [0.01, 0.13], p = 0.016,
Std. beta = 0.07)
  - The effect of learning [notlearn] is statistically non-significant and negative (beta = -0.04, 95% CI [-0.09,
0.01], p = 0.126, Std. beta = -0.04)
