rtnorm.RdRandom sampling from one-sided truncated normal distribution
rtnorm(mu, sd, MIN)
| mu | The mean parameter of the truncated normal. NOTE that this is NOT equal to the mean of the distribution |
|---|---|
| sd | The standard deviation parameter of the truncated normal. Again, NOTE tht this is not the SD of the distribution. |
| MIN | The minimum value, which defines the truncation. |
Numeric length one.
Draws a random number and, if it doesn't fall within the specified range, resample using an adjusted Normal CDF. This isn't performed immediately because CDF sampling calls three functions -- qnorm, runif, and pnorm--and therefore is much less efficient than a simple random sample.
