1 The model The simple linear regression model for nobser vations can be written as yi= β 0 β 1xiei, i= 1,2,··· ,n (1) The designation simple indicates that there is only one predictor variable x, and linear means that the model is linear in β 0 and β 1The intercept β 0 and the slope β 1 are unknown constants, and. 46,X, i(X)(q10) Abnormal female bone marrow chromosome analysis with one normal X chromosome, and one longarm isochromosome X derivative The latter is formed by the centromeric fusion of two copies of the long arm (q) of the X chromosome i(X)(q10), also written i(Xq) or iso(Xq). In the above equation we get E = V x I x t energy = voltage x current x time We can also use the word work instead of the word energy because work done = energy transferred so you might see the equation energy = voltage x charge E = V x Q written as work = voltage x charge W = V x Q See all equations for electricity How is Potential.
