Question
In using ESOA techniques the term spatial outlier refers to ___. groups of points or enumeration units that do not display any type of patterns points or enumeration units that have significantly high or low z-scores for a particular attribute. pairs of point or enumeration units that exhibit high-high and low-low relationships using the Local Moran's I metric. points or enumeration units whose values are much different than the other points/enumeration units around it. A LISA refers to __________. a statistic that measures spatial auto-correlation for each enumeration unit in relation to its 1 nearest neighbor The result of this statistics can be a high-high high-low low-high or low-low if there is a significant difference between the 2 values a statistic that measures spatial auto-correlation for an entire data set. As a result one value is returned for the entire data set that can be compered to other sets of data a measurement which compares 2 variables to determine if they can and should be used in regression analysis because of then relationship to each other. a statistic that measures spatial auto-correlation tor each enumeration unit in relation to its neighbors (however we define neighborhood) A checkboard pattern is a typical ___ auto-correlation. high-low negative randomly distributed positive The idea being the idea of spatial lags is that ____. Instead of mapping independent values, residuals should mapped to see where values deviated most from our expected model to make conclusions. people make the unfair assumption that relationships derived at one scale can be applied to individual households. some phenomena are spatially contiguous and that values in one enumeration unit affect the values in other units. The values in these adjacent regions must be accounted for. Analysis should be performed at multiple scales (block group and tract) to ensure the result of analysis (Getis-Ord Gi*) align with each other at these scales. In this paper which of the following variable(s) was not positively correlated with child maltreatment rates in Southern California? Imigrant Population/Child Care Burden Education Attainment Housing Stress DisadvantageExplanation / Answer
Q1)ESDA technique is to use a scatterplot with the area attribute value on the vertical axis against the average of the attribute values in the adjacent areas in the horizontal axis
The ESDA technique uses scatterplot technique for detecting spatial outlier where the spatial outlier referes to extreme in terms of attribute sense.
Thus,the correct answer is option B as it relates to extreme attribute values.
Q2)LISA is local indicator of spatial autocorrelation and thus measured Spatial autocorrelation by calculating the local Moran's I.Thus the correct answer is option D.
Q3)In a checkboard pattern there exists a typical negative autocorrlation.Thus the answer is option B.
q4)The idead behind the spatial lag is that for a given neighbourhood i,represents the affect of one unit change in other.Thus the correct answer is option C
Q5)Based on the paper which has incomplete information as I cannot see the article or the paper("In this paper")
