Sequential risk‐efficient estimation of the parameter in the uniform density

International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 6, Page 415-423, 2000., 2000
We develop a risk‐efficient sequential procedure for estimating the parameter θ of the uniform density on (0, θ). We give explicit expressions for the distribution of the stopping time and derive its expectation and variance. We also tabulate the values of the expected stopping time and its standard deviation for some selected values of the parameter ...

Sequential point and interval estimation of scale parameter of exponential distribution

International Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 2, Page 383-390, 1995., 1995
Sequential fixed‐width confidence intervals are obtained for the scale parameter σ when the location parameter θ of the negative exponential distribution is unknown. Exact expressions for the stopping time and the confidence coefficient associated with the sequential fixed‐width interval are derived.

Fixed accuracy confidence intervals for variance under first-order stationary autoregressive processes

Research in Statistics
A sequential procedure is developed to construct a fixed accuracy confidence interval (CI) of the common unknown variance of the random observations, where the observations arise from a first-order stationary autoregressive (AR(1)) process with a ...

Optimal precision of coarse structural nested mean models to estimate the effect of initiating ART in early and acute HIV infection

Journal of Causal Inference
Time-dependent coarse structural nested mean models (coarse SNMMs) were developed to estimate treatment effects from longitudinal observational data. Coarse SNMMs estimate the combined effect of multiple treatment dosages and are thus useful to estimate ...
