web en.wikipedia.org Linear regression is an approach for modeling two-dimensional sample points with one independent variable and one dependent variable (conventionally, the x and y coordinates in a Cartesian coordinate system) and finds a linear function (a non-vertical straight line) that, as accurately as possible, predicts the dependent variable values as a function of the independent variables.

web www.sequenceontology.org Structural unit composed of a nucleic acid molecule which controls its own replication through the interaction of specific proteins at one or more origins of replication ( SO:0000340 ).
web www.sequenceontology.org The definition of variant here originates from Sequence ontology ( variant_of ). This element can represent amino acid or nucleic sequence change(including insertion,deletion,SNP,etc.) It can represent some complex mutation or segment variation with the assist of CIGAR string.
web www.sequenceontology.org An allele is one of a set of coexisting sequence variants of a gene ( SO:0001023 ). Nucleotide(s)/amino acids from start position of sequence to stop position of sequence on the positive (+) strand of the observed sequence. When the sequence type is DNA, it should be the sequence on the positive (+) strand. This will lay in the range between variant.start and variant.end.
