- Lumber strength properties vary with changes in moisture
content.
Moisture content adjustment program allows you to predict a
property of dimension lumber at a target moisture content given that
you know the value of the property at an initial moisture content.
(Developed by James Evans and Vicki Herian)
- NONPAR - Nonparametric estimation program
calculates nonparametric estimates of percentiles, associated
confidence intervals, and tolerance limits of the percentiles from a
data set. It can also give order statistics needed for any samples
size to create the same estimates. (Developed by James Evans, Vicki
Herian, and Angela Mitchell)
- A program to calculate Weibull, Normal, and Lognormal estimates of
percentiles from a data set. This program also calculates confidence
intervals and tolerance limits for the percentiles. (Developed by
James Evans and Vicki Herian)
- A program to calculate the
K needed for parametric one-sided
tolerance bounds for normal distributions. (Developed by Steve
Verrill)
- A program to calculate
the order statistic that corresponds to
the one-sided, lower, nonparametric tolerance bound on a quantile.
(Developed by Steve Verrill)

- Fire retardant strength degradation
program
- Calculates kinetic parameter estimates and plots predictions of
in-service fire retardant treated wood. (Developed by Patti Lebow)

- The drying schedule program (Developed
by Steve Verrill and Bill Simpson)

- The board feet to cubic feet ratio
estimation program program (Developed
by Steve Verrill, Vicki Herian, and Henry Spelter)

- The predictor sort program (Developed by Steve Verrill and Vicki Herian)

estimation for general linear models (Developed by Steve Verrill)

- Obtain an exact two-sided confidence interval for the coefficient of variation of a normal distribution (Developed by Steve Verrill)
- Obtain an exact one-sided lower confidence bound on a coefficient of variation of a normal distribution (Developed by Steve Verrill)

- Perform a likelihood ratio test of the
hypothesis that
*k*normally distributed populations share the same coefficient of variation (Developed by Steve Verrill and Rich Johnson) - Obtain confidence bounds on a coefficient of
variation shared by
*k*normally distributed populations (Developed by Steve Verrill and Rich Johnson)

- Obtain asymptotically efficient
estimates of the parameters of a bivariate
Gaussian--Weibull reliability distribution, and perform simulations
to obtain estimates of the actual coverages of the associated asymptotic
confidence intervals. (Developed by Steve Verrill)

- Many "glitchy" regressions applets
(Developed by Steve Verrill)
- simple regression
- example using the QR decomposition
- example using nonlinear least squares

- Java regression,
linear algebra, optimization, quadrature, cumulative distribution function, and random number generation software
(Developed by Steve Verrill)
