Cannot typeset an equation correctly
Cannot typeset an equation correctly
I'm trying to typeset the following equation, but I get complaints about 'missing $ inserted'.
beginequation labelPearson
begintabulary 18cmL R @ >$c<$ @ L
&Sim_a,b^PCC& =
& $displaystyle frac
sum_Pin P( r_a,p - overline ra)( r_b,p - overlinerb) %
sqrtsum_Pin P( r_a,p - overlinera)^2
sqrtsum_Pin P( r_b,p - overlinerb)^2$
endtabulary
endequation
L
R
tabulary is designed for tables with large amounts of text to adjust line breaking, you almost certainly should not be using it here at all, this seems to be a math alignment so align or aligned would be more suitable. the error is because you have math markup _ and ^ in the R column which is a text column.– David Carlisle

@daleif tabulary columns are LCR (but using `tabulary with math is somewhat strange!)

I can see no reason for employing a 4-column tabulary environment; an equation environment is all you need.
tabulary
equation
I would, though, replace all instances of overline with bar. And it should be sum_pin P rather than sum_Pin P, and barr_a and barr_b rather than barra and barrb, right?
overline
bar
sum_pin P
sum_Pin P
barr_a
barr_b
barra
barrb
If you have several equations which need to be aligned on their respective = symbols, do look into employing the align environment (provided by the amsmath package).

(1) Welcome, (2) full minimal example please. How are
L, 'R` etc defined? NMormally these are lower case. (3) You have math in call 2, doesRtake case of this? Now you know why we always ask for a full minimal example that others can copy and test withoput adding anything or having to guess.– daleif
