The Mann-Kendall test and Theil-Sen regression are typically used to detect temporal trend when analyzing environmental data. Both tests are affected by any value chosen to represent non-detects. Another method that is not affected by non-detects is Akritas-Theil-Sen nonparametric regression.
Conduct an evaluation of surface temperature change using temperature measurements that have been collected at Kremsmünster Abbey in Austria, which is considered to be one of the highest quality, longest running, instrumental temperature records in the world.
Landscapes contain complex spatial patterns in the distribution of resources that vary over time. This post examines the spatial analysis of landscapes using base R functions complemented by contributed packages for spatial pattern analysis and for quantifying landscape characteristics.
This post presents single-well iterative thinning, which is a method to determine an optimal sampling frequency for groundwater monitoring wells and monitoring constituents.
Use a stochastic partial differential equation (SPDE) approach with Integrated Nested Laplace Approximation (INLA) to model the spatio-temporal behavior of PM10 concentrations measured in the North-Italian region of Piemonte.
