p.alt |
The alternative proportion in a one-sample test. |
n |
The sample size in a one-sample test. |
p |
The null proportion in a one-sample test. Default is 0.5. |
power |
The desired power level. Default is 0.80. |
alpha |
The desired alpha level - probability of a Type I error. Default is 0.05. |
alternative |
Nature of alternative hypothesis. One of "two.sided", "greater", "less". |

This function can be used to calculate sample size, power or minimum
detectable difference. It determines what to compute base on the
arguments provided. If p.alt
is given, but n
is not, then
sample size is computed. If p.alt
is given along with n
,
then the power is computed. If only n
is provided, the minimum
detectable difference is computed using the default power of 0.80.
A data.frame
containing the power, sample size and all of the
input which was used to perform the computations.
