Techniques of time series data analyses developed over the past decades are reviewed. We discuss the theoretical principles and mathematical descriptions of these analytical techniques that have been developed by scientists with different backgrounds and perspectives. These principles not only provide the guidelines to evaluate each particular technique but also point to directions for the deve...

In order to reduce the Gibbs phenomenon exhibited by the partial Fourier sums of a periodic function f , defined on [−π, π], discontinuous at 0, Driscoll and Fornberg considered so-called singular Fourier-Padé approximants constructed from the Hermite-Padé approximants of the system of functions (1, g1(z), g2(z)), where g1(z) = log(1 − z) and g2(z) is analytic, such that Re (g2(e)) = f(t). Conv...

This paper presents an application of a recently developed methodology for the identification and analysis of flat surfaces affecting rock masses using 3D LiDAR point clouds(Riquelme et al., 2013 submited). The used methodology has been applied to calculate the algebraic equations of the different discontinuities of a rock slope through a methodology based on next three steps: (a) local curvatu...

This paper describes a new and cost effective method of analyzing hard rock discontinuities from oriented core bore hole data. This algorithm uses multivariate cluster analysis to group discontinuities (joints) into sets based on orientation and spatial position (spacing) along the bore hole, and to display the data in a three dimensional stereonet. Although drift or surface exposure mapping da...

The ability of regression discontinuity (RD) designs to provide an unbiased treatment effect while overcoming the ethical concerns plagued by Random Control Trials (RCTs) make it a valuable and useful approach in education evaluation. RD is the only explicitly recognized quasi-experimental approach identified by the Institute of Education Statistics to meet the prerequisites of a causal relatio...

We study the effect of incorporating heterogeneity into default rules by examining the choice between retirement plans at a firm which transitioned from a defined benefit (DB) to a defined contribution (DC) plan. The default plan for existing employees varied discontinuously depending on their age. Employing regression discontinuity techniques, we find that the default increased the probability...

Regression discontinuity models, where the probability of treatment jumps discretely when a running variable crosses a threshold, are commonly used to nonparametrically identify and estimate a local average treatment effect. We show that the derivative of this treatment effect with respect to the running variable is nonparametrically identified and easily estimated. Then, given a local policy i...

We evaluate a “girl-friendly” primary school program in Burkina Faso using a regression discontinuity design. After 2.5 years, the program increased enrollment by 19 percentage points and increased test scores by 0.41 standard deviations. For those caused to attend school, scores increased by 2.2 standard deviations. Girls’ enrollment increased by 5 percentage points more than boys’ enrollment,...

This paper attempts to understand the structure underlining the weakness of the Indonesian economic development strategy in a systemic perspective. The explanation assumes the importance of industrial technological capability within the framework of the techno-economic structure. The results of a simulated model of techno-economic administration show the weakness of the industrial technological...
