Examples

# Convert a time series into a data frame with indices
ds <- data.frame(y = as.ts(CET), t = 1:length(CET))

# Retrieve the coefficients from a null model
tbl_coef(lm(y ~ 1, data = ds))

# Retrieve the coefficients from a two changepoint model
tbl_coef(lm(y ~ (t >= 42) + (t >= 81), data = ds))

# Retrieve the coefficients from a trendshift model
tbl_coef(lm(y ~ poly(t, 1, raw = TRUE) * (t >= 42) + poly(t, 1, raw = TRUE) * (t >= 81), data = ds))

# Retrieve the coefficients from a quadratic model
tbl_coef(lm(y ~ poly(t, 2, raw = TRUE) * (t >= 42) + poly(t, 2, raw = TRUE) * (t >= 81), data = ds))
