normEndp function

Representation of normally distributed endpoints

Represents normally distributed endpoints in clinical trials.

normEndp(mu, sigma)

Arguments

• mu: vector of the expected responses of the treatment groups, should have length K

  (i.e. one entry for each treatment group).

• sigma: vector of the standard deviations in each treatment group, should have length K (i.e. one entry for each treatment group).

Returns

A S4 object that represents a normally distributed endpoint in a clinical trial

Details

The normEnd function is a constructor function for an S4 object of the class normEnd representing a normally distributed endpoint in a clinical trial. In conjunction with the assess function, normal endpoints admit the calculation of the exact type-I-error probability and power.

Examples

# set the parameters of two normally distributed endpoints
endp <- normEndp(mu = c(1, 2), sigma = c(1, 1))
