Type of Transformation

Select the type of transformation to perform on the specified variables.

The types of transformation are summarized in the following table:

Transformation	Description
(blank)	No transformation
exp2	Exponential (base 2)
exp	Exponential (base e)
exp10	Exponential (base 10)
log2	Logarithm (base 2)
log	Logarithm (base e)
log10	Logarithm (base 10)
logistic	exp(x)/[1=exp(x)]
logit	Natural logarithm (base e)
neglog2	Negative logarithm (base 2)
neglog	Negative logarithm (base e)
neglog10	Negative logarithm (base 10)
probit	Returns the corresponding quantile from the standard normal distribution. Note: The value submitted into probit() shall between 0 and 1.
probnorm	Returns the probability that an observation from the standard normal distribution is less than or equal to the submitted value.
recipexp2	Reciprocal exponential (base 2)
recipexp	Reciprocal exponential (base e)
recipexp10	Reciprocal exponential (base 10)
sqrt	Square root
