Data_limits_and_constraints

The limits and constraints discussed here are for Bioequivalence and Linear Mixed Effects modeling.

Cell data may not include question marks (?) or either single (') or double (“) quotation marks.

Variable names must begin with a letter. After the first character, valid characters include numbers and underscores (my_file_2). They cannot include spaces or the following operational symbols: +, –, *, /, =. They also cannot include parentheses (), question marks (?), semicolons (;), single or double quotes.

Titles (in Contrasts, Estimates, or ASCII) can have single or double quotation marks but not both.
