Regression Template
•Regression parameters are derived from four sources.
•The actual area frame survey provides the variable 'y', which is farmer reported acres of some given crop/cover type, within each of 'n' sampled segment areas.
•Sampled segment areas are then located in the categorized data; the variable 'x' comes from counting pixels categorized to that crop type within the segment boundaries.
•The parameter 'b' (or slope) is calculated as a relationship between the x's and y's for each stratum.
•The area frame itself gives the number (known as 'N') of all possible segments in the analysis area.
•Finally classification of full scenes allows counting of all pixels categorized to the given crop within the entire analysis area.
