It is often required to make some inferences about some parameter of the population on the basis of available data. Such inferences are very important in hydrology and hydroclimatology where the available data is generally limited. This is done through hypothesis testing. However, hypothesis testing requires the knowledge of sampling distribution o...

Analysis of road accidents is crucial to understand the factors involved and their impact. Accidents usually involve multiple variables like time, weather conditions, age of driver, etc. and hence it is challenging to analyze the data. To solve this problem, we use Multiple Correspondence Analysis (MCA) to first, filter out the most number of varia...

We study a class of $K$-encoder hypothesis testing against conditional independence problems. Under the criterion that stipulates minimization of the Type II error exponent subject to a (constant) upper bound $\epsilon$ on the Type I error rate, we characterize the set of encoding rates and exponent for both discrete memoryless and memoryless vecto...
To make decisions based on a model fit by Auto-Encoding Variational Bayes (AEVB), practitioners typically use importance sampling to estimate a functional of the posterior distribution. The variational distribution found by AEVB serves as the proposal distribution for importance sampling. However, this proposal distribution may give unreliable (hig...

Soil moisture (SM) plays a crucial role in altering climate extremes through complex land-atmosphere feedback processes. In the
present study, we investigated the impact of SM perturbations on temperature extremes (ExT) over India for the historical period
(1951–2010) and future climate projection (2051–2100) under 4 K warming scenario. We note that more than 70% area of the
Indian landmass has experienced significant changes in characteristics of ExT due to SM perturbations. In particular, we see larger
impact of SM perturbations on ExT over the north-central India (NCI), which is a hotspot of strong SM-temperature coupling. Over
NCI, a 20% departure in SM significantly revamps frequency, duration and intensity of ExT by 2–5 events/year, 1-2 days/event and
0.5–2.1 °C, respectively, through modulating surface energy partitioning, evapotranspiration and SM memory. Importantly, the
impact of SM perturbations on frequency and duration of ExT events becomes less prominent with intensification of global
warming.
