Categorical Analysis (Agresti) VS Hosmer Lameshow

[lyton80]

I have taken a Data Analysis class during a Masters program in Epidemiology which required HL as prescribed text. I am currently enrolled in a doctoral program in Biostatistics and required to take some masters level biostatistics classes. Currently, I am contemplating taking Categorical Data Analysis (Agresti). I am having second thoughts about this since it looks quite similar to my Epi. Data Analysis Class. I would want to rather step into something new e.g. Advance Clinical Trial or Bayesian Statistics. Below is my biostatistics courses profile:

Biostatistics I( Rosner), Biostatistics II( Kutner), Data Analysis (Hosmer and L), Survival Analysis (Klein and Moeshberger), Probability (Casella and Burger;  Chapter 1:5). Anticipated: Mathematical Statistics ( Casella and Berger; Chapter 5:?), Categorical/Bayesian/Advance Clinical Trial
