Probability Functions<br />

Johnson Sb Quantile(p, gamma, delta, theta, sigma)<br />

Description<br />

Returns the quantile whose value for which the probability is p that a random value would be lower.<br />

Arguments<br />

p The probability of the quantile desired; p must be between 0 and 1.<br />

gamma Shape parameter that can be any value.<br />

delta Shape parameter that must be greater than 0.<br />

theta Location parameter that can be any value.<br />

sigma Scale parameter that must be greater than 0.<br />

Johnson Sl Density(q, gamma, delta, theta, sigma)<br />

Description<br />

Returns the density at q of a Johnson Sl distribution.<br />

Arguments<br />

q A value that is in the interval theta to +infinity.<br />

gamma Shape parameter that can be any value.<br />

delta Shape parameter that must be greater than 0.<br />

theta Location parameter that can be any value.<br />

sigma Parameter that defines if the distribution is skewed positively or negatively. Sigma must be equal<br />

to either +1 (skewed positively) or -1 (skewed negatively).<br />

Johnson Sl Distribution(q, gamma, delta, theta, sigma)<br />

Description<br />

Returns the probability that a Johnson Sl-distributed random variable is less than q.<br />

Arguments<br />

q A value that is in the interval theta to +infinity.<br />

gamma Shape parameter that can be any value.<br />

delta Shape parameter that must be greater than 0.<br />

theta Location parameter that can be any value.<br />

sigma Parameter that defines if the distribution is skewed positively or negatively. Sigma must be equal<br />

to either +1 (skewed positively) or -1 (skewed negatively).<br />

Johnson Sl Quantile(p, gamma, delta, theta, sigma)<br />

Description<br />

Returns the quantile whose value for which the probability is p that a random value would be lower.<br />

Arguments<br />

p The probability of the quantile desired; p must be between 0 and 1.<br />

gamma Shape parameter that can be any value.
