get_deltamethod_std_err | R Documentation |
Delta method for approximating the standard error of a transformation g(X) of a random variable X = (x1, x2, ...), given estimates of the mean and covariance matrix of X.
get_deltamethod_std_err( fit_is_lq, variable = c("dose", "fraction_partial", "fraction_hetero"), mean_estimate, cov_estimate, protracted_g_value = NA, d0 = NA )
fit_is_lq |
Whether the fit is linear quadratic ( |
variable |
Variable resulting of the transformation g(X). |
mean_estimate |
The estimated mean of X. |
cov_estimate |
The estimated covariance matrix of X. |
protracted_g_value |
Protracted G(x) value. |
d0 |
Survival coefficient of irradiated cells. |
Numeric value containing the standard error of the dose estimate.
