Assessing the need for transformation of response variables

Creator:

Oregon State University. Forest Research Laboratory, Sabin, Thomas E., and Stafford, Susan G.

Abstract:

Violations of one or more of the assumptions made In analysis of variance (ANOVA) or linear regression analysis may lead to erroneous results. Often data will not conform to the assumptions implicit in the analyses, but transforming the data to a different scale may lead to an appropriate model. Before...

Supercritical fluid (SCF) treatment: Its effect on bending strength and stiffness of ponderosa pine sapwood

Creator:

Smith, Susan M., Demessie, E. Sahle, Morrell, Jeffrey J., Levien, Keith L., and Ng, Harry

Abstract:

Adverse effects on mechanical properties from using a supercritical fluid (SCF) to increase preservative penetration of refractory woods were evaluated by treating small ponderosa pine sapwood specimens with supercritical carbon dioxide at 64 combinations of temperatures (35 to 80 C), pressure (1,000 to 4,000 psig), and time (0.5 to 2...
