fixef: Extract the fixed effects coefficients.

In L-Ippel/SEMA: Streaming Expectation Maximization Approximation

Description

This function returns the estimated fixed coefficients.

Usage

fixef(x)

Arguments

x	The sema output, a list with unit parameters.

Value

A data frame with fixed effect coefficients.

Examples

## First we create a dataset, consisting of 2500 observations from 20 
## units. The fixed effects have the coefficients 1, 2, 3, 4, and 5. The 
## variance of the random effects equals 1, 4, and 9. Lastly the 
## residual variance equals 4:
  
test_data <- build_dataset(n = 2500, 
                           j = 20, 
                           fixed_coef = 1:5, 
                           random_coef_sd = 1:3, 
                           resid_sd = 2)
                           
## Next, we fit a simple model to these data                           
m1 <- sema_fit_df(formula = y ~ 1 + V3 + V4 + V5 + V6 + (1 + V4 + V5 | id), 
                    data_frame = test_data, 
                    intercept = TRUE)
fixef(m1)
