Your first task is to determine which numerical information to present in a paper. What a statistics program gives you: For a simple regression (one independent variable), statistics programs produce two estimates, a (the "constant term") and b (the "linear coefficient"), for the parameters α and β, respectively. The presentation of a logistic regression analysis looks very similar to the presentation of results from an OLS multiple regression. In this case, the value is .501, which is not far off from .509, so it is good. ��:�t�F3F# ;��Q�X֍��K�b�Β0[R����݇��!�����w)����Mu��-��&�Z+s�öILX3w�\\�z�p�ϊ��P��#m&4��DW�i׽ީ1���&�+�����jq�C��(�P �+a�ц����b�J�"�D �d���C�b]�c�_�qQ�S� �h��|�篾lnvU��z��J�S�Nf'˔\$�l�_+�w�l�'DM�~�);@S�U�Ʈ0G~ײ�7����I�ev`�s���p5���I?���nR,f �*d�����ːjR��Z������3��� A simple linear regression was calculated to predict weight based on height.
