Cooper Sloan commented on MADLIB-1091: -------------------------------------- Can you give the database version and madlib version please? > Linear regression fails in merge for groups with small number of rows > --------------------------------------------------------------------- > > Key: MADLIB-1091 > URL: https://issues.apache.org/jira/browse/MADLIB-1091 > Project: Apache MADlib > Issue Type: Bug > Components: Module: Linear Regression > Reporter: Rahul Iyer > Fix For: v1.12 > > > Issue reported by user: > {quote} > Hi all! I'm trying to run madlib's linear regression on a table with a group > by column for a client engagement. There are 44.5M distinct values in the > group by column and 14 data points for each group by value. Each regression > should be very simple since its only 14 points but I'm getting an error: > {code} > Function "madlib.linregr_merge_states(madlib.bytea8,madlib.bytea8) is > improperly aligned for alignment request in seek()" > {code} > Tested it on a few rows and it worked. Any idea what might be causing this > error or what this error means? > {quote} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
