Hello! Here's what I have: In a new notebook type in the following:
data = {{12,1},{7,2},{8,3},{5,4},{3,5}};
Needs["Statistics`LinearRegression`"]; reg = Regress[data, {1, a}, a];
Chop[reg, 10^-3]
Here's what I get:
Regress::"shdw":
"Symbol \!\(\"Regress\"\) appears in multiple contexts \
\!\({\"Statistics`LinearRegression`\", \"Global`\"}\); definitions in
context \
\!\(\"Statistics`LinearRegression`\"\) may shadow or be shadowed by
other \ definitions."
Regress[{{12,1},{7,2},{8,3},{5,4},{3,5}},{1,a},a]
Why does Mathematica display the error?
