General Spatial Stats Concepts Pt 2

Question 1

Cross-k function

Answer 1

are the point patterns in phenomenon x related to patterns in phenomenon y?

Question 2

G-function

Answer 2

alternative of Ripley’s K

Describes clustering in point patterns by looking at the likelihood that given a distance (d), the nearest neighbor is within that distance

Question 3

L-function

Answer 3

transforms Ripley’s K so that the expected value has a slope of 1

Question 4

polygon continuity

Answer 4

like rook/queen/bishop

looking at how they spatially interact

Question 5

Spatial autocorrelation

Answer 5

Likelihood of values of a point in space being similar to values close by

Question 6

positive spatial autocorrelation

Answer 6

values near to one another are more likely to be similar

Question 7

negative spatial autocorrelation

Answer 7

values near to one another are more likely to be dissimilar

Question 8

Rook weighting model

Answer 8

4 cells directly around the origin cell

Question 9

Bishop weighting model

Answer 9

4 cells at the diagonal cells around an origin cell

Question 10

Queen weighting model

Answer 10

all 8 cells around an origin (bishop + rook)
