The Long Term Resource Monitoring Program (LTRMP) sampling design and statistics web pages describe LTRMP sampling designs and present design-based methods for estimating status and trends from LTRMP monitoring data. Design-based estimation methods rely on properties of the sampling design, and therefore are typically viewed as less subjective than estimates from statistical models. The following link leads to web pages that provide technical guidance for estimating means and temporal trends using LTRMP data:

The following links provide background information on LTRMP sampling designs and analyses that may be helpful when estimating means and temporal trends:

The following links cover statistical topics not strictly associated with design-based estimation:
