I have a data set of 48 row and 5 column. Like the following Year Month Water_Demand Population rainfall, data for 4 years (48 months). Here water_demand is dependent variable and population and rainfall are independent variables. I estimate the regression coefficients four times, each time excluded 12 months from the data set.Here is the code, number_of_lines=length(data); C = zeros(3,4); for n=[1 13 25 37] under_test=data; under_test(n:n+11,:)=; B1=under_test(:,3); B2=under_test(:,4); B3=under_test(:,5); x1=[ones(size(B1)),B2,B3]; y1=B1; C(:,n)=regress(y1,x1); end now i want to get standard error, R2, adjusted R2 of those four run. Can any one help plz.thanks.
