background: the aim of present study was to determine the influence of stress management on affective control and distress tolerance in mothers of children with sensory-motor disabilities. methods: this current study was a study with pretest-posttest and treatment group. the thirty mothers of children with sensory-motor disabilities were selected from sensory-motor disabilities center in qum by...

A density ratio is defined by the ratio of two probability densities. We study the inference problem of density ratios and apply a semi-parametric density-ratio estimator to the two-sample homogeneity test. In the proposed test procedure, the f -divergence between two probability densities is estimated using a density-ratio estimator. The f -divergence estimator is then exploited for the two-sa...

By using the brute force algorithm, the application of the two-dimensional two-sample Kolmogorov–Smirnov test can be prohibitively computationally expensive. Thus a fast algorithm for computing the two-sample Kolmogorov–Smirnov test statistic is proposed to alleviate this problem. The newly proposed algorithm is O(n) times more efficient than the brute force algorithm, where n is the sum of the...

We consider the inequality $f \geqslant f\star f$ for real integrable functions on $d$ dimensional Euclidean space where $f\star denotes convolution of $f$ with itself. show that all such are non-negative, which is not case same in $L^p$ any $1 < p \leqslant 2$, defined. also solutions satisfy $\int f(x){\rm d}x \tfrac12$. Moreover, if = \tfrac12$, then must decay fairly slowly: |x| \infty$, an...

In this article we relate two different densities. Let F k be the free group of finite rank k ≥ 2 and let α be the abelianization map from F k onto Z k. We prove that if S ⊆ Z k is invariant under the natural action of SL(k, Z) then the asymptotic density of S in Z k and the annular density of its full preimage α −1 (S) in F k are equal. This implies, in particular, that for every integer t ≥ 1...
