Alpha to Probabilities

Calculates the cumulative probabilities of confidence limits associated with the specified significance level/s \(\left( \alpha \right)\) for a two-tailed test.

alpha2prob(alpha = c(0.001, 0.01, 0.05))

Arguments

alpha	Numeric vector. Significance level \(\left( \alpha \right)\) . By default, alpha is set to conventional significance levels alpha = c(0.001, 0.01, 0.05).

Value

Returns probabilities associated with the specified significance level/s \(\left( \alpha \right)\) for a two-tailed test. The results are sorted from smallest to largest.
