Plot cv_poisson_rt

Plot cv_poisson_rt

Usage

# S3 method for class 'cv_poisson_rt'
plot(x, which_lambda = c("cv_scores", "lambda.min", "lambda.1se"), ...)

Arguments

x

result of cv_estimate_rt of class cv_poisson_rt

which_lambda

select which Rt's to plot.

If not provided, the cross validation score will be plotted. If provided a list of lambda, the corresponding Rt estimation will be plotted.

If provided a string, it must be either one of lambda.min, lambda.1se, or cv_scores.

• If provided lambda.min, plot Rt which is generated from the lambda that minimizes the cross validation score.

• If provided lambda.1se, plot Rt which is generated from the lambda whose corresponding cross validation score is 1 standard error away of the minimal cross validation score.

• If provided cv_scores, plot the cross validation score.

• If NULL, all estimated Rt values are plotted.

Not used.

Value

a ggplot2::ggplot

Examples

y <- c(1, rpois(100, dnorm(1:100, 50, 15) * 500 + 1))
cv <- cv_estimate_rt(y, korder = 1, nfold = 3, nsol = 30)
plot(cv)

plot(cv, which_lambda = cv$lambda[1])

plot(cv, which_lambda = "lambda.min")

plot(cv, which_lambda = "lambda.1se")

plot(cv, NULL)
