I first apply the simple linear regression with one independent variable and one dependent variable. However, it fits bad. I would like to now what model is appropriate for data distribution like this? Or what can I do to improve the fit?</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Capture.PNG" style="width: 862px;"><img src="https://communities.sas.com/t5/image/serverpage/image-id/48561i118B13AE5CB0E3E4/image-size/large?v=v2&amp;px=999" role="button" title="Capture.PNG" alt="Capture.PNG" /></span></P> Sat, 22 Aug 2020 22:03:25 GMT https://communities.sas.com/t5/Statistical-Procedures/Need-help-with-model-choosing/m-p/678706#M32589 gx2144 2020-08-22T22:03:25Z Re: Need help with model choosing https://communities.sas.com/t5/Statistical-Procedures/Need-help-with-model-choosing/m-p/678707#M32590 <P>This variable cannot be used to predict the response (other than poorly).</P> <P>&nbsp;</P> <P>You need to try a different variable.</P> <DIV id="tap-translate">&nbsp;</DIV> Sat, 22 Aug 2020 22:06:57 GMT https://communities.sas.com/t5/Statistical-Procedures/Need-help-with-model-choosing/m-p/678707#M32590 PaigeMiller 2020-08-22T22:06:57Z Re: Need help with model choosing https://communities.sas.com/t5/Statistical-Procedures/Need-help-with-model-choosing/m-p/678737#M32595 <P>Your data look like a X correspond to many Y .
