[Tex/LaTex] Name of Y-like symbol in LaTeX

Question

I can't find the name of this symbol:

It doesn't seem to be a Greek letter, and I have also tried using the \mathcal command. Does anyone know it?

UPDATE

The symbol used in a context:

I think this is just the uppercase Y in mathpazo:

\documentclass[11pt]{article}
\usepackage[margin=3.4cm]{geometry}
\usepackage{mathpazo}
\begin{document}
\noindent
Let $i=1,\ldots,N$ denote the $N$ experimental units
and $Y_i$ the $i$'th response variable.
Now we also supose that we have a covariate $x_i$ for
each experimental unit.
The experiment can be with one or more factors, with or
without blocks, and almost any experimental design.
However, in order to illustrate the use of the covariate
we consider a single \linebreak
factor and a one-way analysis of a
variance model in the situation where the covariate was
not used.  Let $\mathtt{TREAT}$ be the factor in the
experiment with the $k$ levels $\mathtt{treat}_1$, $\ldots$,
$\mathtt{treat}_k$.  If $\mathtt{TREAT}_i$ denotes the
treatment of the $i$'th experimental unit, so that
$\mathtt{TREAT}_i$ is identical to one of the treatments
$\mathtt{treat}_1$, $\ldots$, $\mathtt{treat}_k$, we can write
the one-way analysis of variance model as
\[
  Y_i = \alpha(\mathtt{TREAT}_i) + \epsilon_i,
\]
supplemented with the usual assumptions that $\epsilon_1,
\ldots,\epsilon_N$ are independent and normally
distributed with the same variance $\sigma^2$.
