Survival analysis refers to methods for the analysis of data in which the outcome denotes the time to the occurrence of an event of interest. Survival curves show, for each time plotted on the X axis, the portion of all individuals surviving as of that time. Kaplan-Meier cumulative mortality curves. In a t-test or regression the analysis is based around the estimation of and testing hypotheses about population parameters, which are numbers such as means, standard deviations or regression slopes. While these are all great modern tools for data analysis, the vast majority of asset modeling in the industry still makes use of statistical time series analysis. Your analysis shows that the results that these methods yield can differ in terms of significance. See note above.
