+# Plots of the dimensions
+
+## Setup 
+We consider the matrix $QQ^\top$ and look at the smallest eigenvalue, i.e. the
+smallest non-zero singular value of $Q$.
+
+The matrix $Q$ is given by
+$$
+Q_{ik} = \int_{\frac{k}{K}}^{\frac{k+1}{K}} p_a(u| X_i) \, du
+$$
+with
+$$
+p_a(u|X) = \frac{f_v(F_a^{-1}(u) - a^\top X)}{f_a(F_a^{-1}(u))}
+$$
+
+## Plots of n vs. k
+
+- The $v$'s are normally distributed with $v \sim \mathcal N(0,1)$
+- Plot $n = 100, 200, 300, 400$ and $k = 1, \dots, K$ with $K = \sqrt n$.

+The data for $n = 100$ is covered by the data for $n = 200$.
+
+## Analysis of the convergence
+
+We assume that the smallest singular value $\sigma$ can be approximated by:
+$$
+\sigma = C \cdot n^\eta \cdot k^\kappa \cdot a^\alpha
+$$
+to estimate the coefficients we make a log-transform and perform a linear regression, i.e.
+$$
+\log(\sigma) = \log (C) + \eta \log(n) + \kappa\log(k) + \alpha \log(a).
+$$
+
+```{r estimate coeffs}
