Examples of loess

• The loess procedure is not appropriate for time-series data which are necessarily serially correlated.

• Specifically, the loess procedure is a regression technique for serially uncorrelated data with independent realizations of a random variable.

• A significant positive correlation was found between adult catch and larval infestation on foliage in sandy fields but not in loess.

• The line was fitted by loess to the baseline days.

• No such correlation was detected in loess fields.

• A similar, but non-significant, trend was evident on loess.

• The lack of correlation between infestation parameters on loess may be due to high larval mortality caused by the relatively high moisture content of this soil type.

• Alternatively, infested tubers in loess may support more larvae than those in sand, possibly because cracks in loess soil make the tubers accessible to more larvae.
