I have the highlighted sentence showing up in Overleaf using LaTex using the following text/code:
where $\Phi_2$ corresponds to CDF of the bivariate normal distribution with expectation zero, unit variances, and correlation coefficient $\rho$$\in$[−1,1] 
However, I am getting the error:
LaTeX Error: Unicode character − (U+2212)
What am I doing wrong? How do I fix the error?
